'Ashamed' in the Bible

Therefore, do not be ashamed of the testimony about our Lord, nor me his prisoner, but suffer along with [me] for the gospel, according to the power of God,

for which reason also I suffer these [things]. But [I am] not ashamed, because I know in whom I have believed, and I am convinced that he is able to guard [what] I have entrusted until that day.

May the Lord grant mercy to the household of Onesiphorus, because he refreshed me many times, and was not ashamed of my imprisonment,

Make every effort to present yourself approved to God, a worker having no need to be ashamed, guiding the word of truth along a straight path.
