Genesis 4:3-4

And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering:

Proverbs 15:8 ; Psalms 11:7 . See, also, particularly, Hebrews 11:4 , which, at once, proves that Abel knew under what character the promised Seed should come; and, therefore, by faith in that redemption, he brought his offering. Sweet and precious testimony to the truth as it is in Jesus!
