goats' hair
Compare (Leviticus 16:5); (Leviticus 16:7-10).
The reference seems to be to the result of the ordinance of the two goats as "covering"
( See Scofield) - (Leviticus 16:5)
thus speaking of Christ in atonement
( See Scofield) - (Genesis 3:21).
This thought is intensified in the colour of the rams' skins, (Exodus 26:14).
