(verb chanakh, "educate" (Pr 22:6), with adjective chanikh (Ge 14:14)): In 1Ki 10:2 the ’s "train," the noun is chayil, the usual word for "force," "army." But in Isa 6:1 the "train" (shul, "loose hanging garment") is that of God’s robe (the margin "skirts").
tran, trand: The word is used in two places in both the and the (British and American), namely, Ge 14:14, where it means "drilled," "prepared for war," and Pr 22:6. "Train up a child" means more than to teach, and includes everything that pertains to the proper development of the child, especially in its moral and spiritual nature. In this broader sense also the Revised Version (British and American) substitutes "train" for the "teach" of the King James Version in Tit 2:4 (sophronizo).
