3 "Hear, you kings! Give ear, you princes! I, (even) I, will sing to Yahweh. I will sing praise to Yahweh, the God of Israel.

Hear, O ye kings; give ear, O ye princes,.... Not only the neighbouring ones, but all the kings and princes of the earth, far and near, then and in succeeding ages; Deborah desires and wishes that all potentates might hear of the wonderful works of God done for his people, that they might learn to know there is one that is higher than they, to whom all the amazing things done in the world are to be ascribed; and be cautious how they oppressed the people of God, since sooner or later he would avenge them on them. The Targum restrains this to the kings that came with Sisera and the governors with Jabin; but if there were any such, as it is not improbable there were, see Judges 5:19; yet it is most likely that they were slain with them: there are some, as Kimchi observes, who think this respects the people of Israel, who were all the sons of kings; but the first sense is best:
I, even I, will sing unto the Lord, I will sing praise to the Lord God of Israel: which are the words of Deborah particularly, and the repetitions serve to express how cordial, earnest, and vehement she was in her praise and thankfulness to God; thereby setting an example to others, encouraging them to the same practice, and directing persons of every rank and quality to give praise only to Jehovah, the self-existing, everlasting, and unchangeable Being; to him who is the Lord and God of Israel in a peculiar manner, and not to any of the gods of the Gentiles.
3 Hear, ye kings; give ear, ye princes!
I, to the Lord will I sing,
Will sing praise to the Lord, the God of Israel.
4 Lord, when Thou wentest out from Seir,
When Thou marchedst out of the fields of Edom,
The earth trembled, and the heavens also dropped;
The clouds also dropped water.
5 The mountains shook before the Lord,
Sinai there before the Lord, the God of Israel.
The "kings and princes" are not the rulers in Israel, for Israel had no kings at that time, but the kings and princes of the heathen nations, as in Psalm 2:2. These were to discern the mighty acts of Jehovah in Israel, and learn to fear Jehovah as the almighty God. For the song to be sung applies to Him, the God of Israel. זמּר, ψάλλειν, is the technical expression for singing with an instrumental accompaniment (see at Exodus 15:2).
The princes - You especially that live near, and have evil designs against Israel, know this for your caution, and terror too, if you presume to molest them. God of Israel - Who, as you see by this plain instance, is both able and resolved to defend them from all their enemies.
