that ye should remember the words which were spoken before by the holy prophets, and the commandment of the Lord and Saviour through your apostles:

by recalling what was foretold by the holy prophets and commanded by our Lord and Savior through your apostles.

to be mindful of the sayings said before by the holy prophets, and of the command of us the apostles of the Lord and Saviour,

to be mindful of the words spoken before by the holy prophets, and of the commandment of the Lord and Saviour by your apostles;
