Despite the predominant function of the king as a military leader, the Bible records many occasions when the kings of Israel and Judah fulfilled a significant role in the leadership of the nation’s worship.
The King As Warrior
In the ancient world, kings were primarily military leaders, commanding their armies in warfare (Gen. 14:8–9:2; Josh. 12; 1 Sam. 11:1; 2 Sam. 8:1–6; Job 15:24; Prov. 30:29–31). The kings of Israel and Judah were no exceptions; their major preoccupation was the defense of their nation or the conquest of neighboring kingdoms. Their association with warfare, as well as their lack of priestly status, normally precluded their involvement in the leadership of worship. Saul, fresh from victory over the Philistines, felt the wrath of Samuel because he had offered a burnt offering himself when Samuel’s arrival at Gilgal was delayed (1 Sam. 13:8–14). David was told not to build the temple because he was a man of war who had shed much blood (1 Chron. 22:8; 28:3). Uzziah was successful in warfare and strengthened Judah’s defenses; when he presumed to burn incense to the Lord in the temple, however, he was opposed by the priests and became leprous (2 Chron. 26:16–21).
The King As Covenant Mediator
The religious problem of the Israelite monarchies was that, in terms of the covenant, Yahweh himself was king. Indeed, the covenant structure of Israelite worship was modeled after that of the ancient Near Eastern treaty between a “great king” and his vassals, a pattern that placed the Lord in the position of the king. Worship focused on the kingship of Yahweh, as in the “enthronement psalms” (Pss. 29; 47; 93; 95–99). The ark itself was a visible symbol of Yahweh’s kingship. Moreover, the treaty-covenant structure also placed his worshipers in the position not of slaves but of vassals or subkings—a “kingdom of priests,” among whom the earthly king was one worshiper among many, subject like all others to the covenant laws. Thus the covenant theology of divine kingship acted as a corrective to any spiritual pretense on the part of the ruler and served as a platform on which the prophets, especially, might stand in rebuking and correcting an errant monarch. Thus, Elijah could throw back in Ahab’s face the epithet “troubler of Israel” (1 Kings 18:17–18); and Isaiah could accuse Ahaz of trying the patience of God (Isa. 7:13).
The theological “problem” with the preeminent kingship of Yahweh was partially resolved in Judah by the theological solution of royal sonship, in which the earthly ruler was seen as the adopted son of Yahweh, and as his vice-regent in government. In Psalm 2, for example, the king speaks prophetically, repeating the Lord’s decree of adoption: “You are my Son; today I have become your Father” (Ps. 2:7). Possibly such materials were composed for the coronation ceremonies, when the Lord would declare, “I have installed my King on Zion, my holy hill” (Ps. 2:6). Psalms 72, 101, and 110 also may relate to the same occasion, as might other passages, such as Isaiah’s oracle, “to us a son is given, and the government will be on his shoulders” (Isa. 9:6). The identification of king and priest is clear in the prophetic declaration, “You are a priest forever, in the order of Melchizedek” (Ps. 110:4). Here the psalmist relates the Judean monarch to the Canaanite Melchizedek, who had ruled at the same site in Jerusalem as “king of Salem” and “priest of God Most High” (’El ‘elyon) and to whom Abraham had offered a tithe (Gen. 14:18–20).
As the anointed representative of the Lord, the Judean king was seen by Old Testament writers as a mediator of the covenant between the Lord and his people. The prophet Nathan announced a special covenant relationship between the Lord and the dynasty of David (2 Sam. 7:5–17), proclaiming that his house and kingdom would endure before the Lord. This covenant, however, was made with David as “ruler over my people Israel” (2 Sam. 7:8). David understood “that the Lord had established him as king over Israel and had exalted his kingdom for the sake of his people Israel” (2 Sam. 5:12). Thus the Davidic covenant was a localized manifestation of the basic covenant between Yahweh and his worshipers, with the king serving in the role of mediator. This role was most adequately filled by David himself, but the theology of the Davidic covenant continued to undergird the Judean monarchy and was foundational to the work of the major Judean prophets in their vision of the maintenance and restoration of the covenant (cf. Isa. 9:6–7; Jer. 30:8–9; 33:14–26; Ezek. 34:23–24; 37:24–28) so that the postexilic prophet Zechariah could proclaim that “the house of David will be like God, like the Angel of the Lord going before them” (Zech. 12:8).
Accordingly, despite the restrictions placed on the king as an officiant in sacrifice, the biblical history records occasions when the Judean king legitimately exercised personal leadership in the worship of the Lord. David is most remarkable for his intimate devotion to Yahweh, expressed in his dancing before the ark (2 Sam. 6:14) as it was being brought, at his direction, to Zion, or in his composition of worship materials as the “sweet psalmist of Israel” (2 Sam. 23:1 NASB ). David instituted and organized the Levitical, prophetic worship of the “tent of David” and had the vision for the erection of the house of the Lord (2 Sam. 7:2; 1 Chron. 22). It was left to Solomon, his son, to carry out the actual construction of the temple (1 Kings 5–7; 2 Chron. 2–4). As a priestly king, Solomon personally officiated at the dedication of the sanctuary (1 Kings 8:12–21; 2 Chron. 5), offering extended prayer (1 Kings 8:22–61; 2 Chron. 6) and sacrifices (1 Kings 8:62–66; 2 Chron. 7:1–11).
Kings As Reformers of Worship
Later kings functioned as organizers or reformers of worship and played a secondary role as officiants. Asa carried through a reform instigated by prophecy and led the people in a renewal of the covenant (2 Chron. 15:8–15). Faced with an enemy invasion, Jehoshaphat led the people in penitential worship and instructed the Levitical musicians to lead the army into battle singing praise to the Lord (2 Chron. 20:18–21). Hezekiah, the first king since the time of David to receive the biblical historian’s unqualified commendation (2 Kings 18:1–6), purged the worship of Yahweh of some of its Ba’alistic accretions. Later in the history of Judah, Josiah led the people in a renewal of the covenant, reading aloud the Mosaic Law and covenant (2 Kings 23:1–3). He also purified Israelite worship of its pagan and occult flavor and reinstituted the celebration of the Passover (2 Kings 23:21–23). Sadly, the reforming kings of Judah were in the minority. Most Judean rulers did little to protect the integrity of the covenant of Yahweh. The situation was even worse in the northern kingdom of Israel, where Jeroboam I and Ahab with his consort Jezebel took the lead in the falsification and perversion of worship.
