'Serving' in the Bible

And it was told the king of Egypt that the people were fled: and the heart of Pharaoh and of his servants was changed towards the people, and they said, What is this we have done, that we have let Israel go from serving us?

This is the service of the families of the Gershonites, in serving and in bearing burdens:

But Martha was cumbered about much serving; and she came up to him, and said, Lord, dost thou not care that my sister did leave me to serve alone? bid her therefore that she help me.

serving the Lord with all lowliness of mind, and with tears, and with trials which befell me by the plots of the Jews;

unto which promise our twelve tribes, earnestly serving God night and day, hope to attain. And concerning this hope I am accused by the Jews, O king!

in diligence not slothful; fervent in spirit; serving the Lord;

For we also once were foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, hating one another.
