Luke 20:44

David therefore (Daueid oun). Without ei as in Matthew 22:45 . On the basis of this definite piece of exegesis (oun, therefore) Jesus presses the problem (pw, how) for an explanation. The deity and the humanity of the Messiah in Psalms 110:1 ff. are thus set forth, the very problems that disturbed the rabbis then and that upset many critics today.
