2 Bible Verses about Covenant Made At Sinai

This set of circumstances contains an illustration; for these two women [Hagar and Sarah] represent the two Agreements [between God and mankind]. The one [Agreement], given at Mount Sinai, represents Hagar, whose children became [the Israelites], enslaved under bondage [to the requirements of the law of Moses].

But the minds of the Israelites became dull for, to this very day, the same veil remains on them [i.e., figuratively] when the Old Agreement [Scriptures] are read. It is not being revealed to them that the Old Agreement is being abolished by Christ [i.e., by His death on the cross. See Col. 2:14].
