Albert Barnes Commentary 2 Samuel 6:2

"And David arose, and went with all the people that were with him, from Baale-judah, to bring up from thence the ark of God, which is called by the Name, even the name of Jehovah of hosts that sitteth [above] the cherubim." — 2 Samuel 6:2 (ASV)

From Baale of Judah - See the margin and 1 Samuel 6:21 note.

Whose name ... - The literal rendering is, which is called by the Name, the Name of Yahweh of Hosts, who sits upon the cherubim, that is, the ark which is called after the Lord of Hosts and bears His Name (1 Kings 8:43; Isaiah 4:1).
