Abraham continues his "my wife is my sister" antics with King Abimelech. Family stress continues as the Abraham, Sarah, and Hagar love triangle worsens. Ishmael, the illegitimate son of Abrahams competes with Isaac, but he and his mother Hagar are eventually sent away. God then calls Abraham to sacrifice his son in an ultimate test of faithfulness. This leaves us wondering, "What does covenant have to do with sacrifice?" and "How does this relate to God's promise to Abraham that he will be a blessing to the world?"
