'Shrink' in the Bible

[you know] how I did not shrink back in fear from telling you anything that was for your benefit, or from teaching you in public meetings, and from house to house,

For this is the will of God, that you be sanctified [separated and set apart from sin]: that you abstain and back away from sexual immorality;

Abstain from every form of evil [withdraw and keep away from it].

Now, little children (believers, dear ones), remain in Him [with unwavering faith], so that when He appears [at His return], we may have [perfect] confidence and not be ashamed and shrink away from Him at His coming.
