Luke 10:25

νομικός τις. A teacher of the Mosaic Law—differing little from a scribe, as the man is called in Mark 12:28. The same person may have had both functions—that of preserving and that of expounding the Law.

ἐκπειράζων αὐτόν. Literally, “putting Him fully to the test” (Luke 4:12); but the purpose does not seem to have been so deliberately hostile as in Luke 11:54.

τί ποιήσας ζωὴν αἰώνιον κληρονομήσω; See Luke 18:18, and the answer there also given. It is interesting to compare it with the answer given by St Paul after the Ascension, Acts 16:30-31. Had the ‘lawyer’ known what ‘eternal life’ is (John 3:36; John 5:24; John 6:47; John 17:37, &c.) he would have framed his question very differently.
