Hebrews 1:5 - Wesley's Explanatory Notes

I will be to him a Father, and he shall be to me a Son — I will own myself to be his Father, and him to be my Son, by eminent tokens of my peculiar love The former clause relates to his natural Sonship, by an eternal, inconceivable generation; the other, to his Father's acknowledgment and treatment of him as his incarnate Son. Indeed this promise related immediately to Solomon, but in a far higher sense to the Messiah. Psalms 2:7; 2 Samuel 7:14
