The teaching about guardian angels is not a myth; certain groups of human beings do actually have personal angels. It was in recognition of this that Jesus, in speaking of the children of the heavenly kingdom, said: “Take heed that you despise not one of these little ones, for I say to you, their angels do always behold the presence of the spirit of my Father.”
Close in meaning, found by a language model. A match does not mean the teachings are the same.
Jesus called a little child to himself, and set him in the middle of them and said, “Most certainly I tell you, unless you turn and become as little children, you will in no way enter into the Kingdom of Heaven. Whoever therefore humbles himself as this little child is the greatest in the Kingdom of Heaven. Whoever receives one such little child in my name receives me, but whoever causes one of these little ones who believe in me to stumble, it would be better for him if a huge millstone were hung around his neck and that he were sunk in the depths of the sea.
For he will put his angels in charge of you, to guard you in all your ways.
They were also bringing their babies to him, that he might touch them. But when the disciples saw it, they rebuked them. Jesus summoned them, saying, “Allow the little children to come to me, and don’t hinder them, for God’s Kingdom belongs to such as these. Most certainly, I tell you, whoever doesn’t receive God’s Kingdom like a little child, he will in no way enter into it.”
