"Among the Jews it was customary for children to be brought to some rabbi, that he might lay his hands upon them in blessing; but the disciples thought the Saviour's work too important to be interrupted in this way. When the mothers came desiring Him to bless their little ones, the disciples looked on them with disfavor. They thought these children too young to be benefited by a visit to Jesus, and concluded that He would be displeased at their presence. But the Saviour understood the care and burden of the mothers who were seeking to train their children according to the word of God. He had heard their prayers. He Himself had drawn them into His presence. MH 40.1"
"Then were there brought unto him little children, that he should put his hands on them, and pray: and the disciples rebuked them."
The EGW passage directly recounts the biblical story of Jesus blessing the children, including the disciples' initial disapproval. It's a clear retelling and interpretation of the Matthew passage.
