Matthew 18:2-6

2And He called a child to Himself and set him among them, 3and said, “Truly I say to you, unless you 1change and 2become like children, you will not enter the kingdom of heaven. 4So whoever will humble himself like this child, he is the greatest in the kingdom of heaven. 5And whoever receives one such child in My name, receives Me; 6but 3whoever 4causes one of these little ones who believe in Me to 5sin, it is better for him that a 6heavy millstone be hung around his neck, and that he be drowned in the depths of the sea.
