42. Give to him that asketh thee--The sense of unreasonable asking is here implied (compare Lu 6:30).
      and from him that would borrow of thee turn not thou away--Though the word signifies classically "to have money lent to one on security," or "with interest," yet as this was not the original sense of the word, and as usury was forbidden among the Jews (Ex 22:25, &c.), it is doubtless simple borrowing which our Lord here means, as indeed the whole strain of the exhortation implies. This shows that such counsels as "Owe no man anything" (Ro 13:8), are not to be taken absolutely; else the Scripture commendations of the righteous for "lending" to his necessitous brother (Ps 37:36; 112:5; Lu 6:37) would have no application.
      turn not thou away--a graphic expression of unfeeling refusal to relieve a brother in extremity.
