Hear, you kings; give ear, you princes; I, [even] I, will sing to Yahweh; I will sing praise to Yahweh, the God of Israel.
"Psalms 68:7-9;  Habakkuk 3:3-16, and this passage all relate to the same event and mutually explain each other.  The subject is the march of Israel with the Lord at their head to take possession of Canaan."[10]
