'Effect' in the Bible

So that the Lord may give effect to what he said of me, If your children give attention to their ways, living uprightly before me with all their heart and their soul, you will never be without a man to be king in Israel.

About this house which you are building: if you will keep my laws and give effect to my decisions and be guided by my rules, I will give effect to my word which I gave to David your father.

And the Lord said, How? And he said, I will go out and be a spirit of deceit in the mouth of all his prophets. And he said, Your trick will have its effect on him: go out and do so.
