Commentary for Job 13:7

Will you speak unjustly for God Since you come to contend in the place of God, it is not good that you should speak unjustly.

and will you speak deceitfully for Him? Heb. ולו [usually “to him”]. For His sake will you speak deceitfully? As in (below 33:6), “Behold I am like your mouth for God (לאל),” and like (Deut. 9:28), “to the land that He spoke for them (להם),” for their benefit, and like (Exod. 14:14), “will fight for you (לכם)”; (Jud. 6:31), “Will you contend for the Baal (לבעל)?” (I find it difficult to compare these instances to here [this verse]. Rather, this is analogous to [Num. 17: 5], “through Moses concerning him ]לו[,” concerning Korah.)
