John Gill Commentary Job 22:7

"Thou hast not given water to the weary to drink, And thou hast withholden bread from the hungry." — Job 22:7 (ASV)

You have not given water to the weary to drink
To a weary thirsty traveller, to whom in those hot countries cold water was very refreshing, and which in desert places was not to be had in common, or any where; rich men were possessed of their wells and fountains, and were kept for their own use, and it was a kindness and favour to obtain water of them; and yet a cup of cold water is one of the least favours to be given to a poor man, and to deny it him in distress was very inhuman, and was very far from Job's character:

and you have withholden bread from the hungry :
bread, which strengthens man's heart, and is the staff of life, without which he cannot support; and this is not to be withheld from, but given even to an enemy when hungry; and to deny it to a poor neighbour in such circumstances is very cruel; the charge is, that Job would not give a poor hungry man a morsel of bread to eat; which must be false, being directly contrary to what he strongly asserts, (Job 31:17) .
