Jacob's Stone Pillows

And he lighted upon a certain place, and tarried there all night, because the sun was set; and he took of the stones of that place, and put them for his pillows, and lay down in that place to sleep. Genesis 28:11

Just as Jacob rested on rocks, you too should rest on the Rock of your salvation.

The LORD liveth; and blessed be my rock; and exalted be the God of the rock of my salvation.
2 Samuel 22:47
