And Jacob rose up early in the morning, and took the stone that he had put for his pillows, and {g} set it up for a pillar, and poured oil upon the top of it.

(g) To be a reminder of the vision shown to him.

Wesley's Notes

28:18 He set up the stone for a pillar - To mark the place again, if he came back, and erect a lasting monument of God's favour to him: and because he had not time now to build an altar here, as Abraham did in the places where God appeared to him, Gen 12:7, he therefore poured oil on the top of this stone, which probably was the ceremony then used in dedicating their altars, as an earnest of his building an altar when he should have conveniencies for it, as afterwards he did, in gratitude to God, Ge 35:7. Grants of mercy call for our returns of duty and the sweet communion we have with God ought ever to be remembered.

Jamieson-Fausset-Brown Bible Commentary

18, 19. Jacob set up a stone, etc.-The mere setting up of the stone might have been as a future memorial to mark the spot; and this practice is still common in the East, in memory of a religious vow or engagement. But the pouring oil upon it was a consecration. Accordingly he gave it a new name, Beth-el, "the house of God" (Ho 12:4); and it will not appear a thing forced or unnatural to call a stone a house, when one considers the common practice in warm countries of sitting in the open air by or on a stone, as are those of this place, "broad sheets of bare rock, some of them standing like the cromlechs of Druidical monuments" [Stanley].

Matthew Henry's Concise Commentary

28:16-19 God manifested himself and his favour, to Jacob, when he was asleep. The Spirit, like the wind, blows when and where it listeth, and God's grace, like the dew, tarrieth not for the sons of men. Jacob sought to improve the visit God had made him. Wherever we are, in the city or in the desert, in the house or in the field, in the shop or in the street, we may keep up our intercourse with Heaven, if it is not our own fault. But the more we see of God, the more cause we see for holy trembling before him.
