'Chosen One' in the Bible

Then a voice came out of the cloud, saying, “This is My beloved Son, My Chosen One; listen and obey and yield to Him!”

And will not [our just] God defend and avenge His elect [His chosen ones] who cry out to Him day and night? Will He delay [in providing justice] on their behalf?

Now the people stood by, watching; but even the rulers ridiculed and sneered at Him, saying, “He saved others [from death]; let Him save Himself if He is the Christ (the Messiah, the Anointed) of God, His Chosen One.”
