There are some well known pastors and Christian Youtuber's who say deliverance isn't biblical, generational curses are not biblical.
Here is some of what I found looking in the bible, teaching the law of the altar, the law of generational blessings or curses.

Genesis 26:24
God is speaking about blessings associated with several generations worshiping him, this can also apply in the reverse as curses from worshiping dark gods and spirits.
Genesis 26:2-4
Again we see the law of the altar here and the blessings or curses associated and it affecting several generations.
Exodus 3:16-17
Go and gather the elders of Israel together and say to them, ‘The Lord, the God of your fathers, the God of Abraham, Isaac and Jacob, has appeared to me, saying, “I am indeed concerned about you and what has been done to you in Egypt. So I said, I will bring you up out of the affliction of Egypt to the land of the Canaanite and the Hittite and the Amorite and the Perizzite and the Hivite and the Jebusite, to a land flowing with milk and honey.”’

Exodus 2:24

Exodus 6:3-5

Law of covenants and how it can bless or curse
Exodus 32:13

Law of blessing and generational blessings from the law of the altar
Leviticus 26:42
then I will remember My covenant with Jacob, and I will also remember My covenant with Isaac, and My covenant with Abraham as well, and I will remember the land.
Deuteronomy 1:8
See, I have placed the land before you; go in and possess the land which the Lord swore to give to your fathers, to Abraham, to Isaac, and to Jacob, to them and their descendants after them.’
Generational blessings, law of the altar, law of covenants
Deuteronomy 29:12-13
that you may enter into the covenant with the Lord your God, and into His oath which the Lord your God is making with you today, in order that He may establish you today as His people and that He may be your God, just as He spoke to you and as He swore to your fathers, to Abraham, Is
