Watch ye, stand fast in the faith, quit you like men, be strong.
Their hopes of salvation ought to depend not on Apollos or any teacher: it rests with themselves.
Watch ye - for ye are slumbering.
Stand - for ye are tottering. In the faith - which is assailed by some (1 Corinthians 15:1-2; 1 Corinthians 15:12-17).
Quit you like men, be strong - for ye are effeminate.
Let all your things be done with charity (1 Corinthians 8:1; 1 Corinthians 13:1) - not with strife, as at present.
