Hello, God has given me something in 1 Samuel 2:35 which says, “I will raise up for myself a faithful priest, who will do according to what is in my heart and mind. I will firmly establish his house, and he will minister before my anointed one always.”
So, what God has given me is, that God is talking (through a man) here, and He is saying (to Eli) that He will raise up a new priest who will obey Him (because Eli’s sons were doing evil). Samuel will be that prophet, and he will anoint Saul as priest , and he (Samuel) will worship the “anointed one”, who is Jesus, and Jesus took our sin, and died on the cross for us, so that we could (and can) live.
Also, God is saying that Eli will no longer be priest because his sons were doing evil, which tells us, (or people who have children) to raise up their children in a Godly way, so that the children will do what Samuel did, worship the Lord, and love Him, and always know that Jesus died on the cross for them, and God will bless them, because they trust in Him, and love Him. It also tells children to obey their parents, as long as it is not sin.
