John Trapp on Luke 24:28

Verse 28. And he made as though he would, &c.] So did the Angel to Lot, Gen. 19. 2. See the like, Josh. 8. 5, 6. 1 King. 3. 24. If Salomon might make as though he would do an act that was unlawfull, we may surely do the like in things indifferent. Yet this was never done (as is well observed) but 1 by those that had authority over others. 2 For some singular good to them, with whom they thus dealt.
