For because they trust in lifeless idols they swear wicked oaths and expect to suffer no harm: The connector for may be omitted, but because should be kept since there is a logical relationship between the two lines of this verse. Good News Translation reverses the order of these lines with a clear translation that may serve as a model, but another possible rendering is:

• When they swear to tell the truth, they tell lies and don’t expect to be punished. This is because they put their trust in idols that are not alive.
