Who are the "twelve patriarchs" (Acts 7:8)?
Jacob's twelve sons who founded the twelve tribes of Israel: Reuben,
Simeon, Levi, Judah, Dan, Napthali, Gad, Asher, Issachar, Zebulun, Joseph
and Benjamin (see Genesis 29:31-30:24).
Is Stephen saying that only the twelve sons of Jacob are
"patriarchs"?
"Patriarchs" refer to men who founded or headed a
family or a clan. All Jews, including the Jewish leaders in Stephen's
audience, knew the first three patriarchs of their nation to be Abraham,
Isaac and Jacob (see "patriarch Abraham" in
Hebrews 7:4), so there was no need for Stephen to identify them as such. He
referred to the twelve sons of Jacob as the "twelve
patriarchs" probably because he didn't see the need to list them one
by one as above.
When did God give Abraham "the covenant of circumcision" (Acts 7:8)?
When he was still called "Abram":
When Abram was ninety-nine years old, the Lord appeared
to Abram and said to him, “I am Almighty God; walk before Me and be
blameless... This is My covenant which you shall keep, between Me and you and
your descendants after you: Every male child among you shall be
circumcised; and you
shall be circumcised in the flesh of your foreskins, and it shall be a sign
of the covenant between Me and you." (Genesis 17:1,10-11)
Who are the "patriarchs" in Acts 7:9?
Nine of Jacob's sons - Simeon, Levi, Judah, Dan, Napthali, Gad, Asher,
Issachar and Zebulun - who sold Joseph into slavery (See Genesis 37:12-36).
From what kinds of "troubles" (Acts 7:10) did God deliver Joseph?
God had Joseph sold to Potiphar, the captain of Pharaoh's guards. Potiphar
noticed
God's blessings through Joseph and put him in charge of managing his house. When Potiphar's wife falsely accused Joseph of attempted rape and he ended up in
prison, God prospered him even in prison (see Genesis 39:1-23).
Why did Pharaoh make Joseph "governor over Egypt" (Acts 7:10)?
God gave Pharaoh two troubling dreams and Joseph the ability to interpret
those dreams, which foretold Egypt's forthcoming famine, and pointed to
Joseph's God-given wisdom to manage it (see Genesis 41:1-45).
Did Joseph's interpretation prove true?
Yes, and God used the famine to move the Jews to Egypt, where He grew a
family into a nation.
