For therefore are ye come to your servant He does not mean that they had come designedly, or for the express purpose of seeking to be entertained, as his guests; but he intimates that their coming had occurred opportunely, as if he would say, You have not slipped into this place by chance; but have been led hither by the design and the direction of God.' He, therefore, refers it to the providence of God, that they had come, so conveniently, to a place where they might refresh themselves a little while, till the heat of the sun should abate. Moreover, as it is certain that Abraham spoke thus in sincerity of mind; let us after his examples conclude that, whenever our brethren, who need our help, meet us, they are sent unto us by God.

I will fetch a morsel of bread - This was the third requisite, and is introduced in its proper order; as eating immediately after exertion or fatigue is very unwholesome. The strong action of the lungs and heart should have time to diminish before any food is received into the stomach, as otherwise concoction is prevented, and fever in a less or greater degree produced.
For therefore are ye come - In those ancient days every traveler conceived he had a right to refreshment, when he needed it, at the first tent he met with on his journey.
So do as thou hast said - How exceedingly simple was all this! On neither side is there any compliment but such as a generous heart and sound sense dictate.

And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye (d) come to your servant. And they said, So do, as thou hast said.
(d) As sent by God that I should do my duty to you.

And I will fetch a morsel of bread,.... A piece or a loaf of bread, as De Dieu shows the word signifies; bread being put for all the necessaries of life:
and comfort ye your hearts; eat to refresh your spirits and renew your strength, that ye may be able to pursue your journey: and
after that ye shall pass on your way; I will retard you no longer:
for therefore are ye come to your servant; not that he thought they came this way on purpose to take some refreshment with him, but so it was ordered by the providence of God; and since it was, he desires that they would accept of his invitation:
and they said, so do as thou hast said; they agreed to it, that water should be fetched to wash their feet, and food for them to eat.

for therefore are ye come--No questions were asked. But Abraham knew their object by the course they took--approaching directly in front of the chief sheik's tent, which is always distinguishable from the rest and thus showing their wish to be his guests.
