John Lightfoot on Matthew 18:10

[Their angels in heaven do always behold, &c.] This one may very well expound by laying to it that which is said, Hebrews 1:14, "The angels are ministering spirits, sent to minister for them who shall be heirs of the salvation to come": as if he should say, "See that ye do not despise one of these little ones, who have been received with their believing parents into the gospel-church: for I say unto you, that after that manner as the angels minister to adult believers, they minister to them also."
