Genesis 28:10,12,16-18, 20-22 (AMP)
10 Now Jacob left Beersheba [never to see his mother again] and traveled toward Haran.
12 He dreamed that there was a ladder (stairway) placed on the earth, and the top of it reached [out of sight] toward heaven; and [he saw] the angels of God ascending and descending on it [going to and from heaven].
16 Then Jacob awoke from his sleep and he said, “Without any doubt the Lord is in this place, and I did not realize it.” 17 So he was afraid and said, “How fearful and awesome is this place! This is none other than the house of God, and this is the gateway to heaven.”
18 So Jacob got up early in the morning, and took the stone he had put under his head and he set it up as a pillar [that is, a monument to the vision in his dream], and he poured [olive] oil on the top of it [to consecrate it].
20 Then Jacob made a vow (promise), saying, “If God will be with me and will keep me on this journey that I take, and will give me food to eat and clothing to wear, 21 and if [He grants that] I return to my father’s house in safety, then the Lord will be my God. 22 This stone which I have set up as a pillar (monument, memorial) will be God’s house [a sacred place to me], and of everything that You give me I will give the tenth to You [as an offering to signify my gratitude and dependence on You].”
