Philippians 3:1-2

Amplified Bible, Classic Edition

3 For the rest, my brethren, delight yourselves in the Lord and continue to rejoice that you are in Him. To keep writing to you [over and over] of the same things is not irksome to me, and it is [a precaution] for your safety.

² Look out for those dogs [Judaizers, legalists], look out for those mischief-makers, look out for those who mutilate the flesh.
