Goat

Boyd’s Bible Dictionary:

Several varieties in Palestine, both wild and tame
An important source of food, clothing, and wealth (Gen. 27:99Go now to the flock, and fetch me from thence two good kids of the goats; and I will make them savory meat for thy father, such as he loveth: (Genesis 27:9); 1 Sam. 24:2; 25:22Then Saul took three thousand chosen men out of all Israel, and went to seek David and his men upon the rocks of the wild goats. (1 Samuel 24:2)
2And there was a man in Maon, whose possessions were in Carmel; and the man was very great, and he had three thousand sheep, and a thousand goats: and he was shearing his sheep in Carmel. (1 Samuel 25:2); Job 39:11Knowest thou the time when the wild goats of the rock bring forth? or canst thou mark when the hinds do calve? (Job 39:1)). “Scape-goat,” one of the two offered on Day of Atonement, over which the priest confessed the sins of Israel, and then let it escape to the wilderness (Lev. 16:7-267And he shall take the two goats, and present them before the Lord at the door of the tabernacle of the congregation. 8And Aaron shall cast lots upon the two goats; one lot for the Lord, and the other lot for the scapegoat. 9And Aaron shall bring the goat upon which the Lord's lot fell, and offer him for a sin offering. 10But the goat, on which the lot fell to be the scapegoat, shall be presented alive before the Lord, to make an atonement with him, and to let him go for a scapegoat into the wilderness. 11And Aaron shall bring the bullock of the sin offering, which is for himself, and shall make an atonement for himself, and for his house, and shall kill the bullock of the sin offering which is for himself: 12And he shall take a censer full of burning coals of fire from off the altar before the Lord, and his hands full of sweet incense beaten small, and bring it within the vail: 13And he shall put the incense upon the fire before the Lord, that the cloud of the incense may cover the mercy seat that is upon the testimony, that he die not: 14And he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy seat eastward; and before the mercy seat shall he sprinkle of the blood with his finger seven times. 15Then shall he kill the goat of the sin offering, that is for the people, and bring his blood within the vail, and do with that blood as he did with the blood of the bullock, and sprinkle it upon the mercy seat, and before the mercy seat: 16And he shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness. 17And there shall be no man in the tabernacle of the congregation when he goeth in to make an atonement in the holy place, until he come out, and have made an atonement for himself, and for his household, and for all the congregation of Israel. 18And he shall go out unto the altar that is before the Lord, and make an atonement for it; and shall take of the blood of the bullock, and of the blood of the goat, and put it upon the horns of the altar round about. 19And he shall sprinkle of the blood upon it with his finger seven times, and cleanse it, and hallow it from the uncleanness of the children of Israel. 20And when he hath made an end of reconciling the holy place, and the tabernacle of the congregation, and the altar, he shall bring the live goat: 21And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness: 22And the goat shall bear upon him all their iniquities unto a land not inhabited: and he shall let go the goat in the wilderness. 23And Aaron shall come into the tabernacle of the congregation, and shall put off the linen garments, which he put on when he went into the holy place, and shall leave them there: 24And he shall wash his flesh with water in the holy place, and put on his garments, and come forth, and offer his burnt offering, and the burnt offering of the people, and make an atonement for himself, and for the people. 25And the fat of the sin offering shall he burn upon the altar. 26And he that let go the goat for the scapegoat shall wash his clothes, and bathe his flesh in water, and afterward come into the camp. (Leviticus 16:7‑26)).

Concise Bible Dictionary:

The well-known animal, regarded as clean under the Levitical economy, and having a large place in the sacrifices. Goats formed an important item in the property of the patriarchs. In Daniel’s prophecy of the kingdoms, that of Greece was compared to a “rough he goat,” but with a notable horn between his eyes (Dan. 8:5, 8, 215And as I was considering, behold, an he goat came from the west on the face of the whole earth, and touched not the ground: and the goat had a notable horn between his eyes. (Daniel 8:5)
8Therefore the he goat waxed very great: and when he was strong, the great horn was broken; and for it came up four notable ones toward the four winds of heaven. (Daniel 8:8)
21And the rough goat is the king of Grecia: and the great horn that is between his eyes is the first king. (Daniel 8:21)). The goats, in the sessional judgment of the living nations, represent the lost, in contrast to the saved, who are compared to sheep (Matt. 25:32-3332And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats: 33And he shall set the sheep on his right hand, but the goats on the left. (Matthew 25:32‑33)). THE WILD GOATS were larger animals and lived on the mountains (1 Sam. 24:22Then Saul took three thousand chosen men out of all Israel, and went to seek David and his men upon the rocks of the wild goats. (1 Samuel 24:2); Job 39:11Knowest thou the time when the wild goats of the rock bring forth? or canst thou mark when the hinds do calve? (Job 39:1); Psa. 104:1818The high hills are a refuge for the wild goats; and the rocks for the conies. (Psalm 104:18)).

From Manners and Customs of the Bible:

Sheep and goats are allowed to mingle during the day while at pasturage, but at night are separated. Thus the Saviour seeks to illustrate the truth that though righteous and wicked are now together, there will come a time of separation.
