In 2 Sam. 2:4 David was anointed king over the tribe of Judah. Here David was anointed by the other tribes (vv. 1-5) and established by God as king with his kingdom exalted for the sake of God’s people Israel (vv. 6-25). Saul had tried to exalt himself with his monarchy, but he did not succeed. In contrast, in relation to David God did everything to establish and exalt him and his kingdom for the sake of God’s people (cf. Matt. 23:12). David’s history, particularly the record in 1 Sam. 18:1 through 2 Sam. 5:25, shows that the sovereign God was moving and acting behind the scenes, directing everyone and every situation in order to build up His kingdom in His elect through the proper person for the carrying out of His economy.
