Acts 2:29 Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. Acts 7:8 And he gave him the covenant of circumcision: and so Abraham begat Isaac, and circumcised him the eighth day; and Isaac begat Jacob; and Jacob begat the twelve patriarchs. Acts 7:9 And the patriarchs, moved with envy, sold Joseph into Egypt: but God was with him, Hebrews 7:4 Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils.
