'Begin' in the Bible

And the people and 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 rasor shall come on his head: for the child shall be a Nazarite unto God from the womb: and he shall begin to deliver Israel out of the hand of the Philistines.

And the sons of Benjamin come out to meet the people; they have been drawn away out of the city, and begin to smite some of the people -- wounded as time by time, in the highways (of which one is going up to Beth-El, and the other to Gibeah in the field), are about thirty men of Israel.
