(Hebrews hemah), curdled milk (Genesis 18:8; Judges 5:25; 2 Samuel 17:29), or butter in the form of the skim of hot milk or cream, called by the Arabs kaimak, a semi-fluid (Job 20:17; 29:6; Deuteronomy 32:14). The words of Proverbs 30:33 have been rendered by some "the pressure [not churning] of milk bringeth forth cheese."
