Proverbs 9:3-4 —
Wisdom has sent out her handmaids to invite to the tower, and to the walls of the city.
“If he is a little child, let him come to me.”
Luke 1:38 —
And Mary said, “Behold the handmaid of the Lord; be it done to me according to thy word.”
Matthew 19:13-14 —
Then were little children presented to Him, that He should impose hands upon them and pray. And the disciples rebuked them. But Jesus said to them, “Allow the little children, and forbid them not to come to Me, for the kingdom of heaven is for such.”
The way Proverbs is usually translated nowadays is “the simple,” which in a sense are a “small one” (parvulus in the Latin). But there’s always a strong link between “the simple” and innocence, lack of training, naivete, and youth. (Much like there’s always a strong link between the little people, the poor, the anawim, and God’s children in the Gospel.) Jesus was forever warning people that you had to become like a child to enter the Kingdom; you had to be shrewd like snakes and innocent like doves.
So yes, I think it’s possible that Jesus was making a Proverbs reference when He told His followers to stop rebuking and let the kids come to Him, already.
And that’s the point. The good disciple, like Mary, brings people to her Son. She constantly praises him out of thanks for her own salvation. She constantly invites others and serves them.
