Acts 7:8-10

And God gave Abraham a covenant [a formal agreement to be strictly observed] of [which] circumcision [was the sign]; and so [under these circumstances] Abraham became the father of Isaac, and circumcised him on the eighth day; and Isaac [became the father] of Jacob, and Jacob [became the father] of the twelve patriarchs. [Gen 17:10-14; 21:2-4; 25:26; 29:31-35; 30:1-24; 35:16-26] “The [ten elder] patriarchs, overwhelmed with jealousy, sold [their younger brother] Joseph into [slavery in] Egypt; but God was with him, [Gen 37:11, 28; 45:4] and He rescued him from all his suffering, and gave him favor and wisdom in the sight of Pharaoh, king of Egypt, and he made Joseph governor over Egypt and over his entire household. [Gen 39:2, 3, 21; 41:40-46; Ps 105:21]
