'Serve' in the Bible

And he said to Abram, Know assuredly that thy seed will be a sojourner in a land that is not theirs, and they shall serve them; and they shall afflict them four hundred years.

But also that nation which they shall serve I will judge; and afterwards they shall come out with great property.

And Jehovah said to her, Two nations are in thy womb, And two peoples shall be separated from thy bowels; And one people shall be stronger than the other people, And the elder shall serve the younger.

Let peoples serve thee, And races bow down to thee. Be lord over thy brethren, And let thy mother's sons bow down to thee. Cursed be they that curse thee, And blessed be they that bless thee.

And by thy sword shalt thou live; And thou shalt serve thy brother; And it shall come to pass when thou rovest about, That thou shalt break his yoke from off thy neck.

And Laban said to Jacob, Because thou art my brother, shouldest thou serve me for nothing? tell me, what shall be thy wages?

And Jacob loved Rachel, and said, I will serve thee seven years for Rachel thy younger daughter.

Fulfil the week with this one: then we will give thee the other one also, for the service that thou shalt serve me yet seven other years.
