The first time I noticed this long ago, was when the three angels appeared before Abraham as described in Genesis chapter 18. Also I believe that one of the three angels was Jesus before appearing in the New Testament.
1)The Lord appeared to Abraham near the great trees of Mamre while he was sitting at the day.
2)Abraham looked up and saw three men standing nearby. When he saw them, he hurried from the entrance of his tent to meet them and bowed low to the ground.
3)He said, "If I have found favour in your eyes, my lord(O Lord), do not pass your servant by.
16)When the men got up to leave, they looked down towards Sodom, and Abraham walked along with them to see them on their way.
17)Then the LORD said, "Shall I hide from Abraham what I am about to do?
18)Abraham will surely become a great and powerful nation, and all nations on earth will be blessed through him.
19)For I have chosen him, so that he will direct his children and his household after him to keep the way of the LORD by doing what is right and just, so that the LORD will bring about for Abraham what he has promised him."
20)Then the LORD said, "The outcry against Sodom and Gomorrah is so grievous
21)that I will go down and see if what they have done is as bad as the outcry that has reached me. If not, I will know."
22)The men turned away and went towards Sodom, but Abraham remained standing before the LORD.
そして、イエス様がアブラハムについて語られている箇所があるので載せておきます。
And there are passages where Jesus speaks about Abraham.
