A.T. Robertson Commentary Luke 13:23

"And one said unto him, Lord, are they few that are saved? And he said unto them," — Luke 13:23 (ASV)

Are they few that be saved? (ε ολιγο ο σωζομενοι; ). Note use of ε as an interrogative which can be explained as ellipsis or as ει=η (Robertson, Grammar, p. 1024). This was an academic theological problem with the rabbis, the number of the elect.
