'Servant' in the Bible

Lord Jehovah, thou hast begun to shew thy servant thy greatness, and thy powerful hand; for what God is in the heavens or in the earth that can do like to thy works, and like to thy might?

Let it not seem hard unto thee, when thou sendest him away free from thee; for double the worth of a hired servant hath he been to thee, in serving thee six years; and Jehovah thy God will bless thee in all that thou doest.

Thou shalt not oppress a hired servant who is poor and needy of thy brethren, or of thy sojourners who are in thy land within thy gates:

And Moses the servant of Jehovah died there in the land of Moab, according to the word of Jehovah.
