Matthew Poole and continuators on Genesis 43:29

29 And he lift up his eyes, and saw his brother Benjamin, his mothers son, and said, Is this your younger brother, of whom ye spake unto me? and he said, God be gracious unto thee my son .

(i. e.) More narrowly observed him, having now more leasure, than he seems to have had when he saw him first, ver. 16.

So he calls him, not from special affection, which he intended not yet to discover; but because this compellation is commonly used when a man speaks to another who is his inferiour in age, or dignity.
