'Bond servant' in the Bible

“Now Lord, You are releasing Your bond-servant to depart in peace,According to Your word;

Now a [Roman] centurion’s slave, who was highly regarded by him, was sick and on the verge of death.

When the centurion heard about Jesus, he sent some Jewish elders to Him, asking Him to come and save the life of his slave.

For I also am a man subject to authority, with soldiers under me; and I say to this one, ‘Go,’ and he goes, and to another, ‘Come,’ and he comes, and to my slave, ‘Do this,’ and he does it.”

When the messengers who had been sent returned to the house, they found the slave in good health.

And he said to him, ‘Well done, good servant! Because you proved yourself faithful and trustworthy in a very little thing, you shall [now] have authority over ten cities [in my kingdom].’

At harvest time he sent a servant [as his representative] to the tenants, so that they would give him his share of the fruit of the vineyard; but the tenants beat the servant and sent him away empty-handed.

And one of them struck the slave of the high priest and cut off his right ear.
