The Lord was King over His people, and the man on the throne in Jerusalem was His representative, obligated to lead the people according to the law of God (Deut. 17:14–20). He had to be impartial in his dealings (Ex. 23:3, 6; Deut. 1:17; Isa. 16:5) and make sure that his throne was founded on righteousness and justice (89:14; 92:2). When the Lord asked Solomon what coronation gift he wanted, the inexperienced young man asked for wisdom, and God granted His request (1 Kings 3:1–15). One of his first judgmental decisions revealed this wisdom (1 Kings 3:16–28). Note that righteousness is mentioned four times in verses 1–3 and 7, and see Proverbs 16:12. Messiah will one day reign in righteousness and execute justice throughout the world (Isa. 9:7; 11:4–5; Jer. 23:5–6; Zech. 9:9). In the whole land of Israel, from the mountains to the hills, Solomon’s reign would bring peace and prosperity, for both of these blessings depend on righteousness (Isa. 32:17). It is because Jesus fulfilled God’s righteousness in His life and death that sinners can be forgiven and have peace with God (Rom. 5:1–8), and He is our “King of righteousness” and “King of peace” (Heb. 7:1–3). Solomon’s name is related to the Hebrew word shalom, which means “peace, prosperity, well-being.” The king’s ministry to the poor and afflicted reminds us of the ministry of Jesus (vv. 2, 4, 12–14; Matt. 9:35–38). Early in his reign, Solomon had that kind of concern, but in his later life, his values changed, and he burdened the people with heavy taxes (1 Kings 12:1–16; 4:7; 5:13–15).
“Long live the king!” is the burden of verses 5 and 15, as long as the sun and moon endure (89:29, 36–37; 1 Sam. 10:24; 1 Kings 1:31, 34, 39; Dan. 2:4). God promised David an endless dynasty (2 Sam. 7:16, 19,26), and this was fulfilled in Jesus, the Son of David (Luke 1:31–33). The image of the rain (vv. 6–7) reminds us that a righteous king would encourage righteousness in the people, and a righteous people would receive God’s promised blessings, according to His covenant (Lev. 26:1–13; Deut. 11:11–17; 28:8–14). David used a similar metaphor in 2 Samuel 23:34. Godly leaders are like the refreshing rain that makes the land fruitful and beautiful, so that even the newly mown fields will produce a second crop. They are also like lamps that light the way (2 Sam. 21:17), shields that protect (84:9; 89:16), and the very breath of life that sustains us (Lam. 4:20). Alas, very few of the kings who reigned after David were models of godliness.
