The owner SHALL accept the oath

[tonychanyt]

Le 19:

12 You shall not swear by my name falsely, and so profane the name of your God: I am the LORD.

In ancient Israelite society, oaths were taken seriously.

An example in Ex 22:

10 If a man gives a donkey, an ox, a sheep, or any other animal to be cared for by his neighbor, but it dies or is injured or stolen while no one is watching,

no witnesses

11 an oath before the LORD shall be made between the parties to determine whether or not the man has taken his neighbor’s property. The owner shall accept the oath and require no restitution.

The owner assumed the oath as the truth unless proven otherwise.

12 But if the animal was actually stolen from the neighbor, he must make restitution to the owner.

What was the consequence if someone swore falsely?

He profaned the name of the Lord. He sinned not only against the man whom he wronged but also against God. There was reciprocal punishment for false witnesses. De 19:

18 The judges shall inquire diligently, and if the witness is a false witness and has accused his brother falsely, 19 then you shall do to him as he had meant to do to his brother. So you shall purge the evil from your midst. 20 And the rest shall hear and fear, and shall never again commit any such evil among you. 21 Your eye shall not pity. It shall be life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.

In ancient Israelite society, oaths were taken very seriously.
