And God came to Laban the Syrian in a dream by night, and said unto him, Take heed that thou speak not to Jacob either good or bad.

Wesley's Notes

31:24 Speak not, either good or bad - That is, say nothing against his going on with his journey, for the thing proceedeth from the Lord. The same Hebraism we have, Gen 24:50. The safety of good men is very much owing to the hold God has of the consciences of bad men, and the access he has to them.

King James Translators' Notes

either...: Heb. from good to bad

Matthew Henry's Concise Commentary

31:22-35 God can put a bridle in the mouth of wicked men, to restrain their malice, though he do not change their hearts. Though they have no love to God's people, they will pretend to it, and try to make a merit of necessity. Foolish Laban! to call those things his gods which could be stolen! Enemies may steal our goods, but not our God. Here Laban lays to Jacob's charge things that he knew not. Those who commit their cause to God, are not forbidden to plead it themselves with meekness and fear. When we read of Rachel's stealing her father's images, what a scene of iniquity opens! The family of Nahor, who left the idolatrous Chaldees; is this family itself become idolatrous? It is even so. The truth seems to be, that they were like some in after-times, who sware by the Lord and by Malcham, Zep 1:5; and like others in our times, who wish to serve both God and mammon. Great numbers will acknowledge the true God in words, but their hearts and houses are the abodes of spiritual idolatry. When a man gives himself up to covetousness, like Laban, the world is his god; and he has only to reside among gross idolaters in order to become one, or at least a favourer of their abominations.
