Dictionary of Biblical Words:
By these are meant in Matt. 25, those Gentiles alive on the earth, who at the return of Christ, will be judged for rejecting the testimony of the Jewish messengers, whom the Lord calla his “brethren.” The word is often wrongly used (connected with the erroneous idea of a general judgment) to mean the whole company of the lost, whether dead or alive, by confusing Matt. 25 with Rev. 20:12-15.
“Goat” From Boyd’s Bible Dictionary:
Several varieties in Palestine, both wild and tame
An important source of food, clothing, and wealth (Gen. 27:9; 1 Sam. 24:2; 25:2; 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. 16:7-26).

“Goat” From 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, 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. 25:32-33). THE WILD GOATS were larger animals and lived on the mountains (1 Sam. 24:2; Job 39:1; Psa. 104:18).
Nubian Ibex
“Kid” From Concise Bible Dictionary:
A kid of the goats is constantly mentioned for the sin offering (Num. 7:16-87). As an article of food the kid is considered a dainty: it was with kids that Rebekah prepared the savory meat as venison, wherewith Jacob deceived his father (Gen. 27:9).
