Genesis 44:33

instead of the lad This offer on the part of Judah to remain in Egypt in the bond-service of Joseph, as substitute for Benjamin (LXX ἀντὶ τοῦ παιδίου), forms the noble climax of the generous appeal to Joseph's feelings. The unconscious irony of the situation is heightened by the fact that Judah is unaware of Joseph's personality, and yet has succeeded in making his appeal hinge upon the reference (a) to the old age and affectionate feelings of Jacob, and (b) to the loss which he has already sustained in the death of Benjamin's elder brother.
