(Commentary on Genesis 44:18-34)
Does it mean anything that the last act of Joseph's brothers before he reveals himself to them, is Judah interceding for his brother?
More often than not, to ask the "Is this significant?" question of Scripture is to answer it, "Yes."
After all, it's Judah's Offspring who intercedes for His brothers and gets us off the hook with the Lord. Joseph I think meant to be gracious all along, but he certainly had a way of convicting his brothers of their sin against him. Perhaps the same could be said of God concerning us...
Now read this passage from Hebrews, thinking of Jesus, compared with Judah, interceding for his brother's life.
He is not ashamed to call them brethren, saying:
“I will declare Your name to My brethren;
In the midst of the assembly I will sing praise to You.” [Psalm 22:22]
“I will put My trust in Him.” [Isaiah 8:17; Psalm 18:2; 2 Sam 22:3]
“Here am I and the children whom God has given Me.” [Isaiah 8:18]
Inasmuch then as the children have partaken of flesh and blood, He Himself likewise shared in the same, that through death He might destroy him who had the power of death, that is, the devil, and release those who through fear of death were all their lifetime subject to bondage. For indeed He does not give aid to angels, but He does give aid to the seed of Abraham. Therefore, in all things He had to be made like His brethren, that He might be a merciful and faithful High Priest in things pertaining to God, to make propitiation for the sins of the people. For in that He Himself has suffered, being tempted, He is able to aid those who are tempted.
