And when God caused me to wander from my father’s house, I said to her, ‘This is the kindness you must do me: at every place to which we come, say of me, “He is my brother.”‘” – Genesis 20:13
He clears himself from the imputation of an affront designed to Abimelech in it by alleging that it had been his practice before, according to an agreement between him and his wife, when they first became sojourners (Genesis 20:13): “When God caused me to wander from my father’s house, then we settled this matter.” Note, [1.] God is to be acknowledged in all our wanderings. [2.] Those that travel abroad, and converse much with strangers, as they have need of the wisdom of the serpent, so it is requisite that that wisdom be ever tempered with the innocence of the dove. Matthew Henry.
