Job 34:27

We are not the men to shrink back and be lost, but to have faith and so to win our souls.

On that day, if a man is on the housetop and his goods inside the house, he must not go down to fetch them out; nor must a man in the field turn back

Paul held they should not take a man with them who had deserted them in Pamphylia, instead of accompanying them on active service.

for Demas, in his love for this world, has deserted me and gone to Thessalonica; Crescens is off to Gaul, Titus to Dalmatia,
