King James Version (KJV)
They were armed with bows, and could use both the right hand and the left in hurling stones and shooting arrows out of a bow, even of Saul's brethren of Benjamin.
Modern English
They were bowmen and could shoot arrows and sling stones with either the right or the left hand; they were Benjaminites, Saul's kinsmen.
