'Decided' in the Bible

For I decided not to know anything among you except Jesus Christ and him crucified.

[I have decided] to hand over such a person to Satan for the destruction of the flesh, in order that his spirit may be saved in the day of the Lord.

But he who stands firm in his heart, not having necessity, but has authority concerning his own will, and has decided this in his own heart, to keep his own virgin, he will do well.
