Goat. - Though the sacred writers spoke of the ewe more frequently than of the goat, yet with the latter they were very well acquainted. It was indeed, especially in the hilly regions east of the Jordan, an important item in the wealth of the Israelites. The goat of Israel, particularly the capra membrica, affords numerous illustrations and allusions, Its remarkably long ears are referred to by Amos, iii, 12; its glossy dark hair furnishes a graphic comparison to the author of Cant., iv, 1; vi, 4; this hair was woven into a strong cloth; the skin tanned with the hair on served to make bottles for milk, wine, oil, water, etc. The kid was an almost essential part of a feast. The goat is mentioned in Dan., viii, 5, as the symbol of the Macedonian empire. The grand Gospel scene of the separation of the just and the wicked on the last day is borrowed from the customs of the shepherds in the East.
