'Slave' in the Bible

and whoever wants to be first among you must be a slave to all.

At harvest time he sent a slave to the farmers to collect some of the fruit of the vineyard from the farmers.

But those tenants seized his slave, beat him, and sent him away empty-handed.

Again he sent another slave to them, and they hit him on the head and treated him shamefully.

And one of those who stood by drew his sword, struck the high priest’s slave, and cut off his ear.

Now while Peter was below in the courtyard, one of the high priest's slave girls came by.

When the slave girl saw him, she began again to say to the bystanders, "This man is one of them."
