'Shrink' in the Bible

how I did not shrink from declaring to you anything that was profitable, and teaching you publicly and from house to house,

For I did not shrink from declaring to you the whole purpose of God.

But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul.

Now, little children, abide in Him, so that when He appears, we may have confidence and not shrink away from Him in shame at His coming.
