'Deserted' in the Bible

Of this you are aware, that all the Christians in Roman Asia have deserted me: and among them Phygelus and Hermogenes.

For Demas has deserted me--loving, as he does, the present age--and has gone to Thessalonica; Crescens has gone to Galatia, and Titus to Dalmatia.

At my first defence I had no one at my side, but all deserted me. May it not be laid to their charge.
