What does Genesis 28:13 mean?
Jacob is sleeping in the wilderness, apparently alone, and with only a rock for a pillow. He is on the way to his family's previous homeland in Mesopotamia, both to escape his enraged brother (Genesis 27:41) and to seek a wife (Genesis 28:1–2). While asleep, Jacob is presented with a powerful, unusual dream. The Lord Himself is using this dream to visit Jacob and deliver a moving and personal message.First, the Lord identifies Himself from the top of a "ladder" or "staircase" that reaches from earth to heaven. God assures Jacob that He is, in fact, the God of Abraham, and of Jacob's own father Isaac. He is the same Lord, and He has come to deliver the same words to Jacob as He did to His grandfather.
To begin with, the Lord will give to Jacob and his descendants the very ground on which he is lying. In this way, the Lord acknowledges Jacob's experience while lying there asleep was both a dream and a genuine visitation from God.
