'Effect' in the Bible

And all of these blessings shall come upon you, and {they shall have an effect on you} if you listen to the voice of Yahweh your God:

From the blood of [the] slain, from the fat of [the] mighty, the bow of Jonathan did not turn back, and the sword of Saul did not return {without effect}.

that you not be easily shaken from your composure, nor be troubled either by a spirit or by a message or by a letter {alleged to be from us}, to the effect that the day of the Lord has arrived.

And let endurance have [its] perfect effect, so that you may be mature and complete, lacking in nothing.
