King James Dictionary

Clave To split; to break through; tear. Go ye forth of Babylon, flee ye from the Chaldeans, with a voice of singing declare ye, tell this, utter it even to the end of the earth; say ye, The LORD hath redeemed his servant Jacob. And they thirsted not when he led them through the deserts: he caused the waters to flow out of the rock for them: he CLAVE the rock also, and the waters gushed out. (Isa 48,21)
