C. F. Keil and Franz Delitzsch on Genesis 31:20-21

Gen 31:20-21

“Thus Jacob deceived Laban the Syrian, in that he told him not that he fled;” - לב גּנב to steal the heart (as the seat of the understanding), like κλέπτειν νοο͂ν, and גּנב with the simple accus. pers., Gen 31:27, like κλεπτειν τίνα, signifies to take the knowledge of anything away from a person, to deceive him; - “and passed over the river (Euphrates), and took the direction to the mountains of Gilead.”
