'Sake' in the Bible

So do not be ashamed to testify about our Lord or about me His prisoner, but with me take your share of suffering for the gospel [continue to preach regardless of the circumstances], in accordance with the power of God [for His power is invincible],

The Lord grant mercy to the family of Onesiphorus, because he often refreshed me and showed me kindness [comforting and reviving me like fresh air] and he was not ashamed of my chains [for Christ’s sake];

For this reason I [am ready to] patiently endure all things for the sake of those who are the elect (God’s chosen ones), so that they too may obtain the salvation which is in Christ Jesus and with it the reward of eternal glory.
