Deuteronomy 15:16

I will not go away. Here is the case of a man who became so attached to his master that he preferred to remain (see on Ex. 21:5). When a man thus declined to become free, he voluntarily chose perpetual servitude. This provision, if carried out in conformity to the rules laid down by God (see on v. 15), might prove a blessing to individuals incapable of administering their own affairs. They thus placed themselves permanently under the protection of one who could administer their affairs for them, and who had proved his kindly care of his slaves. The same considerate provisions that had applied to temporary servitude were to be continued.

He loveth thee. Generous and considerate treatment had won the man’s heart. In servitude he had found a measure of freedom sufficient to satisfy him. The motive behind his desire to remain was love.
