I Know Him

Genesis 18:1-2, 16-19

1   And the LORD appeared unto Abraham in the plains of Mamre: and he sat in the tent door in the heat of the day;
2   And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground...

16   And the men rose up from there, and looked toward Sodom: and Abraham went with them to bring them on the way.
17   And the LORD said, Shall I hide from Abraham that thing which I do;
18   Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?
19   For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he has spoken of him.
