God told Moses to consecrate each of the 1st born children and animals in Israel. He did that as a marker to them to help them commemorate this amazing event of the exodus from slavery. The people were still in wonder as they were traveling away from this land that had been their home for nearly 500 years.
God knew that they would need a great number of reminders to stay faithful and to not lose the history and tradition of the exodus. He gave Moses specific instruction to pass on to Israel that would assure His chosen people would never forget where they came from and where they were going to.
Paul gives us the same reminders in his letters to the church. Instruction to forget what is behind and press on toward what is ahead helps us to follow the Lord without questioning His plan. His instruction to not worry but pray with thanksgiving reminds us that God has this! Learn to be content, think on what is true, noble, right, pure, lovely and admirable all are reminders that we need a heavenly focus.
God gives us markers to keep our focus upon Him. That focus is for our sake, not His. If we become distracted, we also get lost and disoriented. Then, the world can destroy us. God knew that was the case for Israel and knows it is the case for us. As Jesus told us in the Sermon on the mount, “Seek first His kingdom and righteousness and all these things will be added to you” Matthew 6:33
God Bless You
The Lord said to Moses, 2 “Consecrate to me every firstborn male. The first offspring of every womb among the Israelites belongs to me, whether human or animal.”
3 Then Moses said to the people, “Commemorate this day, the day you came out of Egypt, out of the land of slavery, because the Lord brought you out of it with a mighty hand. Eat nothing containing yeast. 4 Today, in the month of Aviv, you are leaving. 5 When the Lord brings you into the land of the Canaanites, Hittites, Amorites, Hivites and Jebusites—the land he swore to your ancestors to give you, a land flowing with milk and honey—you are to observe this ceremony in this month: 6 For seven days eat bread made without yeast and on the seventh day hold a festival to the Lord. 7 Eat unleavened bread during those seven days; nothing with yeast in it is to be seen among you, nor shall any yeast be seen anywhere within your borders. 8 On that day tell your son, ‘I do this because of what the Lord did for me when I came out of Egypt.’ 9 This observance will be for you like a sign on your hand and a reminder on your forehead that this law of the Lord is to be on your lips. For the Lord brought you out of Egypt with his mighty hand. 10 You must keep this ordinance at the appointed time year after year.
11 “After the Lord brings you into the land of the Canaanites and gives it to you, as he promised on oath to you and your ancestors, 12 you are to give over to the Lord the first offspring of every womb. All the firstborn males of your livestock belong to the Lord. 13 Redeem with a lamb every firstborn donkey, but if you do not redeem it, break its neck. Redeem every firstborn among your sons.
14 “In days to come, when your son asks you, ‘What does this mean?’ say to him, ‘With a mighty hand the Lord brought us out of Egypt, out of the land of slavery. 15 When Pharaoh stubbornly refused to let us go, the Lord killed the firstborn of both people and animals in Egypt. This is why I sacrifice to the Lord the first male offspring of every womb and redeem each of my firstborn sons.’ 16 And it will be like a sign on your hand and a symbol on your forehead that the Lord brought us out of Egypt with his mighty hand.”
