John Gill Commentary Exodus 2:20

"And he said unto his daughters, And where is he? Why is it that ye have left the man? Call him, that he may eat bread." — Exodus 2:20 (ASV)

And he said to his daughters, and where is he ?
&c.] By the account Reuel's daughters gave of Moses, of his courage and humanity, he was very desirous of seeing him:

why [is it] that you have left the man ?
behind them at the well, and had not brought him along with them; he seemed to be displeased, and chides them, and tacitly suggests that they were rude and ungrateful not to ask a stranger, and one that had been so kind to them, to come with them and refresh himself:

call him, that he may eat bread ;
take meat with them, bread being put for all provisions.
