Malachi 3:17
16 Then those who feared the Lord spoke to one another, and the Lord gave attention and heard [it], and a book of remembrance was written before Him for those who fear the Lord and who esteem His name.
17 "They will be Mine," says the Lord of hosts, "on the day that I prepare [My] own possession, and I will spare them as a man spares his own son who serves him."
