Genesis 49:33

Commanding his sons, to wit, concerning the place of his burial. Whilst he was employed in that most solemn and religious work of blessing his children in the name and by the Spirit of God, he used as reverent a posture as his infirm body would permit, and therefore is supposed to sit upon his bedside with his feet hanging downwards. And when he had finished that great work, and wearied himself with so long speech delivered with a most raised and affected mind, he composed himself to rest, and waited for the comfortable approach of his death, which speedily followed it.
