'Instruct' in the Bible

I will instruct and teach you about how you should live. I will advise you as I look you in the eye.

For the music director; according to the shushan-eduth style; a prayer of David written to instruct others. It was written when he fought against Aram Naharaim and Aram-Zobah. That was when Joab turned back and struck down 12,000 Edomites in the Valley of Salt. O God, you have rejected us. You suddenly turned on us in your anger. Please restore us!

How blessed is the one whom you instruct, O Lord, the one whom you teach from your law,
