'Manager' in the Bible

And Abraham said to his chief servant, the manager of all his property, Come now, put your hand under my leg:

And when evening came, the lord of the vine-garden said to his manager, Let the workers come, and give them their payment, from the last to the first.

And he sent for him and said, What is this which is said about you? give me an account of all you have done, for you will no longer be the manager of my property.

Gaius, with whom I am living, whose house is open to all the church, sends his love, so does Erastus, the manager of the accounts of the town, and Quartus, the brother.
