John Lightfoot on Luke 6:12

[In prayer to God: or In the prayer of God.] Compare this kind of phrase with what is said, Beracoth, fol. 7. 1: "R. Jochanan in the name of R. Jose saith, How doth it appear that the holy blessed God doth pray? From thence, that it is said, I will bring them to my holy mountain and make them joyful in the house of 'my' prayer. It is not said of their prayer, but of 'my' prayer. Whence it follows that the holy blessed God doth pray. But how doth he pray? saith Rabh Zutra Bar Tobijah; Rabh saith, Let it be my good pleasure that my mercy overcome my wrath."

"The holy blessed God made him a tabernacle and prayed in it: as it is said, His tabernacle is in Salem, and his dwellingplace in Zion. Now what doth he say when he prayeth? Let it be my good pleasure that I may see my dwellingplace built."

I cannot but laugh at their triflings, and yet withal observe the opinion that nation had, and compare it with this phrase, the prayer of God. They will have it that God prays, not by way of supplication, but authority: "So let it be." Thus our blessed Lord sometimes, Father, I will, John 17:24. Whether the phrase in this place should be thus interpreted, I do not determine.
