Samuel
Judges 5:15ESV·traditional attribution

the princes of Issachar came with Deborah, and Issachar faithful to Barak; into the valley they rushed at his heels. Among the clans of Reuben there were great searchings of heart.

Matthew Henry Presbyterian @wholebiblehenry

Here, I. Deborah stirs up herself and Barak to celebrate this victory in the most solemn manner, to the glory of God and the honour of Israel, for the encouragement of their friends and the greater confusion of their enemies, Jdg 5:12. 1.

Commenting on Judges 5:12-23

John Gill Reformed Baptist @doctorgill

And the princes of Issachar were with Deborah,.... On Mount Tabor, whither they came to offer themselves to join in the war against Jabin; or to assist with their counsels, the men of this tribe being understanding of the times, to know what Israel ought to do, Ch1 12:32.

Jamieson-Fausset-Brown Reformed @jfbcommentary
