For ye know what commandments we gave you by the Lord Jesus.
"Son of man, I have made you a watchman for the house of Israel; whenever you hear a word from my mouth, you shall give them warning from me.
teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age."
1 Corinthians 9:21
To those outside the law I became as one outside the law--not being without law toward God but under the law of Christ--that I might win those outside the law.
2 Thessalonians 3:6
Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from any brother who is living in idleness and not in accord with the tradition that you received from us.
2 Thessalonians 3:10
For even when we were with you, we gave you this command: If any one will not work, let him not eat.
