And Jesus said, Who has touched me? But all denying, Peter and those with him said, Master, the crowds close thee in and press upon thee, and sayest thou, Who has touched me?

having a form of piety but denying the power of it: and from these turn away.

For certain men have got in unnoticed, they who of old were marked out beforehand to this sentence, ungodly persons, turning the grace of our God into dissoluteness, and denying our only Master and Lord Jesus Christ.
