Butter
(Heb. hemah), curdled milk (Gen 18:8; Judg 5:25; 2 Sam 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; Job 29:6; Deut 32:14). The words of Prov 30:33 have been rendered by some “the pressure [not churning] of milk bringeth forth cheese.”
