OH YES IT DOES

In fact it is the fourth of the ten commandments found in Exodus 34:14-26.

All that openeth the matrix is mine; and every firstling among thy cattle, whether ox or sheep, that is male.
But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem him not, then shalt thou break his neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.

Lest you think I am misquoting this passage, you are invited to see it represented in 19 different translations in the Bible Hub.

NO…. you did not misread or misunderstand. God makes it clear in other verses that he means you should sacrifice your firstborn son!

Exodus 13:2
“Consecrate to me every firstborn male. The first offspring of every womb among the Israelites belongs to me, whether human or animal.“

Exodus 22:29
“Do not hold back offerings from your granaries or your vats. “You must give me the firstborn of your sons.

“But wait!” my Jewish friend exclaims. “That’s not what it says in the Hebrew” he says. “Yes it is!” we say. Have a look for yourself.

Exodus 34:20 in Hebrew
Exodus 13:2 in Hebrew
Exodus 22:29 in Hebrew

And then of course this is confirmed in Leviticus and Numbers.

Leviticus 27:28-29 Notwithstanding no devoted thing, that a man shall devote unto the LORD of all that he hath, both of man and beast, and of the field of his possession, shall be sold or redeemed: every devoted thing is most holy unto the LORD. None devoted, which shall be devoted of men, shall be redeemed; but shall surely be put to death. 

What gibberish but it appears that something that is first born is surely going to be put to death

Numbers 3:13 Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the LORD.

Ahh, much more to the point; all the firstborn in Israel (both man and beast) belong to the LORD, just as they did in Egypt.

Other Instances Where God Permits/Allows/Performs the Sacrifice of Children

God himself sacrifices (murders) all the first born of the Egyptians.

God himself sacrifices (murders) all the first born (and everyone else) in the flood.

God sent a famine on David’s kingdom for three years. When David asked God why, God answered: “It is for Saul, and his bloody house, because he slew the Gibeonites.” To appease God and end the famine that was caused by his predecessor (Saul), David agreed to have two of Saul’s sons and five of his grandsons killed and hung up “unto the Lord.” God stopped the famine after they were killed and hung up for him. 2 Samuel 21:1,8-14

On top of explicitly requiring the death of 7 children hung up unto the Lord, the three year famine would have killed many children since they are the most vulnerable during times of food shortage.

Judges 11:31 Then it shall be, that whatsoever cometh forth of the doors of my house to meet me, when I return in peace from the children of Ammon, shall surely be the LORD’s, and I will offer it up for a burnt offering.

Well, turns out it was Jephthah’s daughter and the loving, merciful God doesn’t stop him! God allows Jephtahah to burn his own daughter – child sacrifice at its best, we say.

And, by the way, the Bible got the easiest moral question that humanity has ever faced wrong. Slavery!
