"To the Jew this form was a significant one. When a Jewish father blessed his children, he laid his hands reverently upon their heads. When an animal was devoted to sacrifice, the hand of the one invested with priestly authority was laid upon the head of the victim. And when the ministers of the church of believers in Antioch laid their hands upon Paul and Barnabas, they, by that action, asked God to bestow His blessing upon the chosen apostles in their devotion to the specific work to which they had been appointed. AA 162.1"
"And Israel stretched out his right hand, and laid it upon Ephraim’s head, who was the younger, and his left hand upon Manasseh’s head, guiding his hands wittingly; for Manasseh was the firstborn."
EGW draws a parallel between the laying on of hands in Acts and the Jewish custom of blessing children and dedicating sacrifices. While not a direct quote or explicit allusion, it uses the Genesis passage (and the general practice) to illustrate the significance of the act.
