CRIB is the modern manger (Luk_2:7), which contained the fodder for oxen (Pro_14:4), asses (Isa_1:3), and doubtless other live stock as well.

(אבוּס, 'ēbhūṣ): ?Crib? translates the Hebrew word 'ēbhūṣ exactly, as it denotes ?a barred receptacle for fodder used in cowsheds and foldyards; also in fields, for beasts lying out in the winter.? The Hebrew is from a word meaning to feed (אבס, 'ābhaṣ), and is used in the precise sense of the English word in Job_39:9 of the ?crib? of the wild ox, in Pro_14:4, ?Where no oxen are, the crib is clean,? and in Isa_1:3, ?The ox knoweth his owner, and the ass his master's crib.?

Pro_14:4 (b) Where no work is undertaken for the Lord, there is no trouble and no blessing. If work is undertaken for the Lord, though it entails much labor, pain and trouble, great blessings will follow.
Isa_1:3 (b) The Lord is teaching us that the ox, which represents the Christian, knows and esteems the one who owns him, as the Christian knows and loves his Lord. The ass, however, who represents the ungodly, the unsaved, is only interested in the gifts that he may receive from his master. The crib is used to represent earthly blessings which earthly people receive and return no gratitude to the GOD who gives them.

Crib
(אֵבוּס, ebus'), a stall or barn where fodder is stored (Pro_14:4) and where cattle are fed (Job_39:9; Isa_1:3); perhaps simply a manger for them to eat out of, as the Sept. and Vulg. render in the last- cited passage. SEE MANGER.
