'Strengthened' in the Bible

Now the sons of Israel again did evil in the sight of the Lord. So the Lord strengthened Eglon the king of Moab against Israel, because they had done evil in the sight of the Lord.

and you will hear what they say; and afterward your hands will be strengthened that you may go down against the camp.” So he went with Purah his servant down to the outposts of the army that was in the camp.

so that the violence done to the seventy sons of Jerubbaal might come, and their blood might be laid on Abimelech their brother, who killed them, and on the men of Shechem, who strengthened his hands to kill his brothers.
