What precautions were carried out by Israelites to celebrate Passover festival?

1. The Israelites were instructed to select a lamb without blemish and slaughter it at twilight on the 14th day of the first month.

2. The blood of the lamb was to be smeared on the doorposts and lintel of their houses as a sign for the Lord to pass over and spare them from the plague that would strike the firstborn of Egypt.

3. The Israelites were to roast the lamb and eat it with unleavened bread and bitter herbs.

4. They were to eat the meal in haste, with their loins girded, sandals on their feet, and staff in hand, ready to leave Egypt at a moment's notice.

5. The Israelites were to eat the entire lamb and not leave any leftovers until morning.

6. They were to observe the Passover as a perpetual ordinance, celebrating it each year as a reminder of their deliverance from slavery in Egypt.

7. The Israelites were also instructed to remove all leaven from their homes before the start of the festival, as leaven symbolized sin and impurity.

8. The Passover festival was to be a time of remembrance and thanksgiving, with the Israelites recounting the story of their deliverance from Egypt and giving thanks to God for his faithfulness and protection.
