Numbers 8:17
For every firstborn male in Israel is Mine, both man and beast. I set them apart for Myself on the day I struck down all the firstborn in the land of Egypt.
For every firstborn male in Israel is Mine,

God claimed Israel’s firstborn because He spared them during the final plague in Egypt. Their consecration preserved the memory of Israel’s deliverance and acknowledged that the nation belonged to Him.

Exo 13:2 “Consecrate to Me every firstborn male. The firstborn”…
Exo 34:19 The first offspring of every womb belongs to Me,…
Exo 22:29 You must not hold back offerings from your granaries…

both man and beast.

The claim extended to livestock as well as people, showing God’s authority over Israel’s households, wealth, and future. Firstborn animals were devoted or redeemed according to the law, while the Levites were taken in place of Israel’s firstborn sons.

Exo 13:15 And when Pharaoh stubbornly refused to let us go…
Exo 13:12 you are to present to the LORD the firstborn male of every womb.…
Exo 11:5 every firstborn son in the land of Egypt will die…

I set them apart for Myself

God designated the firstborn for sacred purposes, separating them from ordinary use. Their status pointed to the holiness required of those belonging to the Lord.

Lev 20:26 You are to be holy to Me because I, the LORD, am holy,…
Exo 19:5 Now if you will indeed obey My voice and keep My covenant,…
Deu 14:2 for you are a people holy to the LORD your God.…

on the day I struck down all the firstborn in the land of Egypt.

The death of Egypt’s firstborn brought Pharaoh’s resistance to an end and secured Israel’s release from slavery. Israel’s survival depended on the blood of the Passover lamb, foreshadowing Christ’s sacrificial death for His people.

Exo 12:29 Now at midnight the LORD struck down every firstborn male…
Exo 12:12 On that night I will pass through the land of Egypt…
Psa 105:36 Then He struck all the firstborn in their land,…

God's Sovereignty and Ownership
God declares ownership over the firstborn, emphasizing His sovereignty over all creation. This reminds us that everything we have is ultimately God's, and we are stewards of His gifts.

In biblical times, the firstborn held a place of honor and responsibility. This principle can remind us of our responsibilities as God's children to live lives that honor Him.

Remembrance of Deliverance
The consecration of the firstborn serves as a perpetual reminder of God's deliverance from Egypt. We are called to remember and celebrate God's deliverance in our own lives through Christ.

Consecration and Holiness
Just as the firstborn were set apart for God, believers are called to live lives of holiness, set apart for God's purposes.

The Cost of Redemption
The death of the firstborn in Egypt foreshadows the ultimate sacrifice of Jesus, the firstborn over all creation, whose death brings redemption to all who believe.

Our Lord's Prayer for his People's Sanctification
In this wonderful prayer, our Lord, as our great High Priest, appears to enter upon that perpetual office of intercession which he is now exercising at the right hand of the Father. Our Lord ever seemed, in the eagerness of his love, to be anticipating his work. Before he was set apart for his life-work, by the descent of the Holy Ghost upon him, he must needs be about his Father's business; before he finally suffered at the hands of cruel men, he had a baptism to be baptized with, and he was straitened

"My Little Children, These Things Write I unto You, that Ye Sin Not. And if any Man Sin, we have an Advocate with the Father,",
1 John ii. 1.--"My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father,", &c. Christ Jesus came by water and by blood, not by water only, but by blood also, and I add, not by blood only but by water also, chap. v. 6. In sin there is the guilt binding over to punishment, and there is the filth or spot that defileth the soul in God's sight. To take away guilt, nothing so fit as blood for there is no punishment beyond blood, therefore

Numbers
Like the last part of Exodus, and the whole of Leviticus, the first part of Numbers, i.-x. 28--so called,[1] rather inappropriately, from the census in i., iii., (iv.), xxvi.--is unmistakably priestly in its interests and language. Beginning with a census of the men of war (i.) and the order of the camp (ii.), it devotes specific attention to the Levites, their numbers and duties (iii., iv.). Then follow laws for the exclusion of the unclean, v. 1-4, for determining the manner and amount of restitution
