15:4 But look, ¹  the word of the Lord came to him: “This man ²  will not be your heir, ³  but instead ⁴  a son ⁵  who comes from your own body will be ⁶  your heir.” ⁷ 

22:15 The Lord’s angel called to Abraham a second time from heaven 22:16 and said, “‘I solemnly swear by my own name,’ ¹  decrees the Lord, ²  ‘that because you have done this and have not withheld your son, your only son, 22:17 I will indeed bless you, ³  and I will greatly multiply ⁴  your descendants ⁵  so that they will be as countless as the stars in the sky or the grains of sand on the seashore. Your descendants will take possession ⁶  of the strongholds ⁷  of their enemies. 22:18 Because you have obeyed me, ⁸  all the nations of the earth will pronounce blessings on one another ⁹  using the name of your descendants.’”
