Moses
Genesis 43:3ESV·traditional attribution

But Judah said to him, “The man solemnly warned us, saying, ‘You shall not see my face unless your brother is with you.’

3. And Judah spake unto him, saying. Judah seems to feign something, for the purpose of extorting from his father what he knew he would not freely grant; but it is probable that many discourses had been held on both sides, which Moses, according to his custom, has not related.

Matthew Henry Presbyterian @wholebiblehenry

Here, 1. Jacob urges his sons to go and buy more corn in Egypt, Gen 43:1, Gen 43:2. The famine continued; and the corn they had bought was all spent, for it is meat that perisheth. Jacob, as a good master of a family, is in care to provide for those of his own house food convenient; and shall not God provide for his children, for the household of faith?

John Gill Reformed Baptist @doctorgill

If thou wilt send our brother with us,.... Give orders for his going with us, and put him under our care: we will go down and buy thee food; signifying, on the above condition, that they were ready and willing to take a journey into Egypt, and buy provisions for him and his family, otherwise not.
