And ye know that with all my power I have served your father.
Genesis 31:38-42
"These twenty years I [have been] with you; your ewes and your female goats have not miscarried, nor have I eaten the rams of your flocks.
"That which was torn [of beasts] I did not bring to you; I bore the loss of it myself. You required it of my hand [whether] stolen by day or stolen by night.
"[Thus] I was: by day the heat consumed me and the frost by night, and my sleep fled from my eyes.
"These twenty years I have been in your house; I served you fourteen years for your two daughters and six years for your flock, and you changed my wages ten times.
"If the God of my father, the God of Abraham, and the fear of Isaac, had not been for me, surely now you would have sent me away empty-handed. God has seen my affliction and the toil of my hands, so He rendered judgment last night."
Genesis 30:29
But he said to him, "You yourself know how I have served you and how your cattle have fared with me.
Ephesians 6:5-8
Slaves, be obedient to those who are your masters according to the flesh, with fear and trembling, in the sincerity of your heart, as to Christ;
not by way of eyeservice, as men-pleasers, but as slaves of Christ, doing the will of God from the heart.
With good will render service, as to the Lord, and not to men,
knowing that whatever good thing each one does, this he will receive back from the Lord, whether slave or free.
Colossians 3:22-25
Slaves, in all things obey those who are your masters on earth, not with external service, as those who [merely] please men, but with sincerity of heart, fearing the Lord.
Whatever you do, do your work heartily, as for the Lord rather than for men,
knowing that from the Lord you will receive the reward of the inheritance. It is the Lord Christ whom you serve.
For he who does wrong will receive the consequences of the wrong which he has done, and that without partiality.
Titus 2:9
[Urge] bondslaves to be subject to their own masters in everything, to be well-pleasing, not argumentative,
Titus 2:10
not pilfering, but showing all good faith so that they will adorn the doctrine of God our Savior in every respect.
1 Peter 2:18
Servants, be submissive to your masters with all respect, not only to those who are good and gentle, but also to those who are unreasonable.
