Matthew 23:3

All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not.

All things therefore whatever they tell you to observe, observe and do, but don't do their works; for they say, and don't do.

all things therefore whatsoever they bid you, `these' do and observe: but do not ye after their works; for they say, and do not.

all, then, as much as they may say to you to observe, observe and do, but according to their works do not, for they say, and do not;

So practice and observe everything they tell you. But do not do what they do, for they do not practice what they preach.
