Genesis 49:33

33.He gathered up his feet. The expression is not superfluous: because Moses wished thereby to describe the placid death of the holy man: as if he had said, that the aged saint gave directions respecting the disposal of his body, as easily as healthy and vigorous men are wont to compose themselves to sleep. And truly a wonderful vigor and presence of mind was necessary for him, when, while death was in his countenance, he thus courageously fulfilled the prophetic office enjoined upon him. And it is not to be doubted that such efficacy of the Holy Spirit manifested itself in him, as served to produce, in his sons, confidence in, and reverence for his prophecies. At the same time, however, it is proper to observe, that it is the effect of a good conscience, to be able to depart out of the world without terror. For since death is by nature formidable, wonderful torments agitate the wicked, when they perceive that they are summoned to the tribunal of God. Moreover, in order that a good conscience may lead us peacefully and quietly to the grave, it is necessary to rely upon the resurrection of Christ; for we then go willingly to God, when we have confidence respecting a better life. We shall not deem it grievous to leave this failing tabernacle, when we reflect on the everlasting abode which is prepared for us.
