'Gained' in the Bible

that no advantage may be gained over us by Satan: for we are not ignorant of his devices.

Make room for us in your hearts. There is not one of you whom we have wronged, not one to whom we have done harm, not one over whom we have gained any selfish advantage.

It is necessary to boast, though nothing is gained by it; but I will go on to visions and revelations of the Lord.

Have I gained any selfish advantage over you through any one of the messengers I have sent to you?
