But you shall open your hand wide unto him, and shall surely lend him sufficient for his need, in that which he lacks.
Read Chapter 15
George Leo Haydock
Need of. The Rabbins understand this of giving freely without any prospect of receiving again, much less of any advantage by usury. They esteem themselves bound also, by the laws of humanity, to assist even idolaters, though they will not beg of such, in public. Some assert, that they never allow public beggars among themselves, and indeed such are seldom to be seen. Yet no law forbids it; and Juvenal (vi. 541,) upbraids them with begging slyly at Rome. Arcanum Judæa tremens mendicat in aurem. (Calmet)
If people be in extreme want, the law requires that necessaries should be given them; but if they be not so far reduced, but that they may be able to pay again in a little time, it may suffice to lend. (Haydock)
