John Calvin on Genesis 35:13

13. And God went up from him. This ascent of God is analogous to his descent; for God, who fills heaven and earth, is yet said to descend to us, though he changes not his place, whenever he gives us any token of his presence; a mode of expression adopted in accommodation to our littleness. He went up, therefore, from Jacob, when he disappeared from his sight, or when the vision ended. By the use of such language, God shows us the value of his word, because, indeed, he is near to us in the testimony of his grace; for, seeing that there is a great distance between us and his heavenly glory, he descends to us by his word. This, at length, was fully accomplished in the person of Christ; who while, by his own ascension to heaven, he raised our faith thither; nevertheless dwells always with us by the power of his Spirit.
