Shall I hide from Abraham? Seeing that God here takes counsel, as if concerning a doubtful matter, he does it for the sake of men; for he had already determined what he would do. But he designed, in this manner, to render Abraham more intent upon the consideration of the causes of Sodom's destruction. He adduces two reasons why He wished to manifest his design to Abraham, before he carried it into execution. The former is, that he had already granted him a singularly honorable privilege; the second, that it would be useful and fruitful in the instruction of posterity. Therefore, in this expression, the scope and use of revelation is briefly noted.

Shall I hide from Abraham - That is, I will not hide. A common mode of speech in Scripture - a question asked when an affirmative is designed. Do men gather grapes of thorns? Men do not gather grapes of thorns, etc.

And the (h) LORD said, Shall I hide from Abraham that thing which I do;
(h) Jehovah the Hebrew word we call Lord, shows that this angel was Christ: for this word is only applied to God.

And the Lord said,.... Either unto Abraham himself, so leading on to what he was about to make known to him; and without supposing this it will be difficult to account for Abraham's intercession for Sodom upon this: or to the two angels with him; not as consulting them whether he should or no do what he next suggests, but to give to them Abraham's just character, and the reasons of his using him in such a friendly manner: or it may be, to the other divine Persons, the Father and Spirit, one with the Son of God, and always present with him:
shall I hide from Abraham the thing which I do? which he was about to do, namely, the destruction of Sodom and Gomorrah: the Jewish writers (a) observe, that these cities were given in the grant of the whole land to Abraham, and therefore it was right to acquaint him with it first: but other and better reasons are given in the next words; Abraham was a friend of the Lord, and he had showed himself friendly to him, not only now, but heretofore, and therefore will treat him as his friend, by imparting his secrets to him.
(a) Targ. Jerus. & Jarchi in loc.

the Lord said, Shall I hide--The chief stranger, no other than the Lord, disclosed to Abraham the awful doom about to be inflicted on Sodom and the cities of the plain for their enormous wickedness.

Shall I hide from Abraham that thing which I do - Thus doth God in his councils express himself after the manner of men, with deliberation. The secret of the Lord is with them that fear him. Those that by faith live a life of communion with God, cannot but know more of his mind than other people. They have a better insight into what is present, and a better foresight of what is to come.
