1 Thessalonians 4:1

Matthew 28:20
and teach them to practice all the commands that I have given you. And I myself will surely be with you all the days, down to the very close of an age."
Mark 13:34
It will be like a man who leaves his home and goes on a journey, after he has given orders to his slaves, to each his particular task, and has given orders to the watchman to keep watch.
2 Thessalonians 3:6-12
Now we charge you, brothers, on the authority of the Lord Jesus Christ, to hold yourselves aloof from any brother who is living as a shirker instead of following the teachings you received from us.
