Genesis 44:6ESV·traditional attribution

When he overtook them, he spoke to them these words.

Matthew Henry Presbyterian @wholebiblehenry

Joseph heaps further kindnesses upon his brethren, fills their sacks, returns their money, and sends them away full of gladness; but he also exercises them with further trials. Our God thus humbles those whom he loves and loads with benefits.

John Gill Reformed Baptist @doctorgill

And he overtook them,.... Their asses being laden with corn could not travel very fast, and he and his attendants being mounted on swift horses: and he spake unto them these same words; that Joseph had ordered him to say, and so what follows particularly, Gen 44:10.

Jamieson-Fausset-Brown Reformed @jfbcommentary

he overtook them, and he spake . . . these words--The steward's words must have come upon them like a thunderbolt, and one of their most predominant feelings must have been the humiliating and galling sense of being made so often objects of suspicion. Protesting their innocence, they invited a search. The challenge was accepted [Gen 44:10-11].
