'Begin' in the Bible

And the people, the princes of Gilead, said one to another, What man is he that will begin to fight against the children of Ammon? he shall be head over all the inhabitants of Gilead.

for, lo, thou shalt conceive, and bear a son; and no razor shall come upon his head; for the child shall be a Nazirite unto God from the womb: and he shall begin to save Israel out of the hand of the Philistines.
