But the man who had been healed did not know who it was, for Jesus had slipped out, since there was a crowd in that place.

So they slipped the anchors and left them in the sea, at the same time loosening the linkage that bound the steering oars together. Then they hoisted the foresail to the wind and steered toward the beach.

Now this matter arose because of the false brothers with false pretenses who slipped in unnoticed to spy on our freedom that we have in Christ Jesus, to make us slaves.

For certain men have secretly slipped in among you -- men who long ago were marked out for the condemnation I am about to describe -- ungodly men who have turned the grace of our God into a license for evil and who deny our only Master and Lord, Jesus Christ.
