'Strengthened' in the Bible

Now the Israelites again did evil in the sight of the Lord, and the Lord strengthened Eglon king of Moab against Israel, since they had done what was evil in the sight of the Lord.

and you will hear what they say; and afterward you will have the courage to go down against the camp.” Then he went down with Purah his servant to the outposts of the army that was in the camp.

so that the violence done to the seventy sons of Jerubbaal (Gideon) might come [on the guilty], and that their [innocent] blood might be laid on Abimelech their brother, who had killed them, and on the leaders of Shechem, who strengthened his hands (encouraged him) to kill his brothers.

But the people, the [fighting] men of Israel, took courage and strengthened themselves and again set their battle line in the same place where they formed it the first day.
