Genesis 40:13 - Matthew Poole's English Annotations on the Holy Bible

Lift up thine head, i.e. advance thee to thy former dignity. So that phrase is used 2 Kings 25:27 Psalms 110:7. Or, reckon thy head, i.e. thy name or thy person, to wit, among his servants, which is added, Genesis 40:20. According to the custom, which was this: at set times governors of families used to take an account of their servants, and to have the names of their servants read to them, and they either left them in the catalogue, or put any of them out, as they saw fit, and inflicted such further punishments upon any of them as they deserved. This seems the truer interpretation, because it is said that Pharaoh lifted up the head of his butler, and of his baker, Genesis 40:20, and therefore the phrase must be so expounded, as to agree equally to both.
