Now it came to pass after these things that God tested Abraham, and said to him, “Abraham!” And he said, “Here I am.” Then He said, “Take now your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you.” Genesis 22:1–2

For where your treasure is, there your heart will be also. Matthew 6:21

And He said, “Do not lay your hand on the lad, or do anything to him; for now I know that you fear God, since you have not withheld your son, your only son, from Me.” Genesis 22:12

And said: “By Myself I have sworn, says the LORD, because you have done this thing, and have not withheld your son, your only son—blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies.” Genesis 22:16–17
