1703. The following places show that the Word describes subservient things as Hebrews. In Moses:

When your Hebrew brother or sister is sold to you, that person shall also serve you six years, and in the seventh year you shall send him or her away free from beside you. (Deuteronomy 15:12)

The word Hebrew is used here because the subject is slavery. In Jeremiah:

At the end of seven years, you shall each send away your Hebrew sister or brother who was sold to you and served you six years. (Jeremiah 34:9, 14)

Here too the word Hebrew is used because the subject is slavery. The children of Jacob are not called Hebrews anywhere else in the prophets. In Samuel:

The Philistines were saying, "Strengthen yourselves and turn into men or you will be slaves to the Hebrews as they were slaves to you." (1 Samuel 4:9)

The same is true here.

[2] In Moses:

Jehovah said to Moses, "Go in to Pharaoh, and you are to speak to him: ‘This is what Jehovah, God of the Hebrews, has said: "Send my people away so that they can serve me."'" (Exodus 9:1, 13; 10:3)

Here again it is because of their enslavement that they are called Hebrews. Potiphar's wife concerning Joseph:

She shouted out to the men of her household and said to them, "See? He has brought us a Hebrew man to mock us." (Genesis 39:14)

He is called a Hebrew because he was a slave there. The chief of the cup bearers said to Pharaoh:

With us was a young Hebrew man, the slave of the chief of the courtiers, and he interpreted our dreams for us. (Genesis 41:12)

In addition, Egyptians called the children of Israel Hebrews because they were slaves, or in servitude, as is known (Exodus 1:15-16, 19, and elsewhere).
