'Took an Oath' in the Bible

And Joseph took an oath of the children of Israel, saying, God will surely visit you, and ye shall carry up my bones from hence.

As Jehovah thy God liveth, there is no nation or kingdom, whither my lord hath not sent to seek thee: and when they said, He is not here, he took an oath of the kingdom and nation, that they found thee not.

And in the seventh year Jehoiada sent and fetched the captains over hundreds of the Carites and of the guard, and brought them to him into the house of Jehovah; and he made a covenant with them, and took an oath of them in the house of Jehovah, and showed them the king's son.

Then said they, We will restore them, and will require nothing of them; so will we do, even as thou sayest. Then I called the priests, and took an oath of them, that they would do according to this promise.
