Isreal & Obedience[/b]S. 2:58-59,[S. 7:161-162] These verses, 58-59, may be compared to vii. 161-162. There are two verbal differences. Here (ii. 58) we have "enter the town" and in vii. 161 we have "dwell in the town." Again in ii. 59 here we have "infringed (Our command)," and in vii. 162, we have "transgressed." The verbal differences make no difference to the sense. (Ali, The Holy Quran-Translation and Commentary, p. 31, f. 72)
