1 Some time later, God tested Abraham’s faith. “Abraham!” God called.“Yes,” he replied. “Here I am.”2 “Take your son, your only son—yes, Isaac, whom you love so much—and go to the land of Moriah. Go and sacrifice him as a burnt offering on one of the mountains, which I will show you.”
Genesis 22:1-2

15 Then he said to them, “You like to appear righteous in public, but God knows your hearts. What this world honors is detestable in the sight of God.
Luke 16:15

3 Fire tests the purity of silver and gold,
    but the Lord tests the heart.
Proverbs 17:3

10 I have refined you, but not as silver is refined.
    Rather, I have refined you in the furnace of suffering.
Isaiah 48:10

7     for he is our God.
We are the people he watches over,
    the flock under his care.
If only you would listen to his voice today!
8 The Lord says, “Don’t harden your hearts as Israel did at Meribah,
    as they did at Massah in the wilderness.
9 For there your ancestors tested and tried my patience,
    even though they saw everything I did.

Psalm 95:7-9

4 On the third day of their journey, Abraham looked up and saw the place in the distance. 5 “Stay here with the donkey,” Abraham told the servants. “The boy and I will travel a little farther. We will worship there, and then we will come right back.”
Genesis 22: 4-5
