New Defender's Study Bible Notes
24:18 forty days and forty nights. It is noteworthy how often this particular time is mentioned in Scripture. It was also the period of maximum rainfall during the great Flood (Genesis 7:4) the period of Elijah’s travel to Mt. Sinai (I Kings 19:8), and the period of Satan’s tempting Christ in the wilderness (Matthew 4:2). Forty days was the period God gave Nineveh to repent under the preaching of Jonah (Jonah 3:4).
