'Strengthened' in the Bible

and thou hast heard what they speak, and afterwards are thy hands strengthened, and thou hast gone down against the camp.' And he goeth down, he and Phurah his young man, unto the extremity of the fifties who are in the camp;

for the coming in of the violence to the seventy sons of Jerubbaal, and of their blood to place it on Abimelech their brother, who slew them, and on the masters of Shechem, who strengthened his hands to slay his brethren.
