'Strengthened' in the Bible

Therefore now let your hands be strengthened, and be ye valiant: for your master Saul is dead, and also the house of Judah have anointed me king over them.

Ahithophel said to Absalom, “Go in to your father’s concubines, whom he has left to keep the house; then all Israel will hear that you have made yourself odious to your father. The hands of all who are with you will also be strengthened.”

You strengthened me with valor sufficient for the battle; you made those who rebelled against me fall beneath me.
