Verse 68. - But chose the tribe of Judah. The choice was made when David was, by God's command, anointed to be king (1 Samuel 16:1-12). The Mount Zion which he loved (comp. Psalm 87:2, "The Lord loveth the gates of Zion more than all the dwellings of Jacob"). God, no doubt, inspired David with the thought of fixing his residence in "the stronghold of Zion" (2 Samuel 5:9), and of bringing up the ark of the covenant into it (2 Samuel 6:12-17). The presence of the ark determined the selection of Jerusalem for the site of the temple.

78:56-72 After the Israelites were settled in Canaan, the children were like their fathers. God gave them his testimonies, but they turned back. Presumptuous sins render even Israelites hateful to God's holiness, and exposed to his justice. Those whom the Lord forsakes become an easy prey to the destroyer. And sooner or later, God will disgrace his enemies. He set a good government over his people; a monarch after his own heart. With good reason does the psalmist make this finishing, crowning instance of God's favour to Israel; for David was a type of Christ, the great and good Shepherd, who was humbled first, and then exalted; and of whom it was foretold, that he should be filled with the Spirit of wisdom and understanding. On the uprightness of his heart, and the skilfulness of his hands, all his subjects may rely; and of the increase of his government and peace there shall be no end. Every trial of human nature hitherto, confirms the testimony of Scripture, that the heart is deceitful above all things, and desperately wicked, and nothing but being created anew by the Holy Ghost can cure the ungodliness of any.But chose the tribe of Judah,.... Both to be the seat of kingly power and government, and of religious worship; the latter is chiefly designed. Jerusalem was, at least part of it, in the tribe of Judah: here David, who was of that tribe, dwelt, and Solomon his son, and all the kings of Judah afterwards; here the temple was built, into which the ark of the covenant was put, and whither the tribes went up to worship

the mount Zion, which he loved; where was the city of David; into which the ark was brought when removed from Gibeah, and on part of which the temple was built: the choice of this place, for such a purpose, was from love, Psalm 87:2, it was typical of the church, the choice of which also arises from the everlasting and unchangeable love of God to it.
