Thou shalt be over my house, and according unto thy {l} word shall all my people be ruled: only in the throne will I be greater than thou.

(l) Some read, the people will kill your mouth, that is obey you in all things.

King James Translators' Notes

be ruled: Heb. be armed, or, kiss

Jamieson-Fausset-Brown Bible Commentary

40. Thou shalt be over my house-This sudden change in the condition of a man who had just been taken out of prison could take place nowhere, except in Egypt. In ancient as well as modern times, slaves have often risen to be its rulers. But the special providence of God had determined to make Joseph governor of Egypt; and the way was paved for it by the deep and universal conviction produced in the minds both of the king and his councillors, that a divine spirit animated his mind and had given him such extraordinary knowledge.

according unto thy word shall all my people be ruled-literally, "kiss." This refers to the edict granting official power to Joseph, to be issued in the form of a firman, as in all Oriental countries; and all who should receive that order would kiss it, according to the usual Eastern mode of acknowledging obedience and respect for the sovereign [Wilkinson].

Matthew Henry's Concise Commentary

41:33-45 Joseph gave good advice to Pharaoh. Fair warning should always be followed by good counsel. God has in his word told us of a day of trial before us, when we shall need all the grace we can have. Now, therefore, provide accordingly. Pharaoh gave Joseph an honourable testimony. He is a man in whom the spirit of God is; and such men ought to be valued. Pharaoh puts upon Joseph marks of honour. He gave him such a name as spoke the value he had for him, Zaphnath-paaneah, a revealer of secrets. This preferment of Joseph encourages all to trust in God. Some translate Joseph's new name, the saviour of the world. The brightest glories, even of the upper world, are put upon Christ, the highest trust lodged in his hand, and all power given him, both in heaven and earth.
