Remember when Moses said to his people: "O my people, remember the favours that God bestowed on you when He appointed apostles from among you, and made you kings and gave you what had never been given to any one in the world. 20 O my people! Enter the holy land which God has promised you; but do not turn back [on your faith,] for then you will be lost!" 21 They said, "O Moses, indeed within it is a people of tyrannical strength, and indeed, we will never enter it until they leave it; but if they leave it, then we will enter." 22 Two men of those who feared (Allah and) on whom Allah had bestowed His Grace [they were Yusha' (Joshua) and Kalab (Caleb)] said: "Assault them through the gate, for when you are in, victory will be yours, and put your trust in Allah if you are believers indeed." 23 They said: "O Moses! while they remain there, never shall we be able to enter, to the end of time. Go thou, and thy Lord, and fight ye two, while we sit here (and watch)." 24 Said he: my Lord I control not but myself and my brother, so decide Thou between us and this transgressing people. 25 He said: 'They shall be forbidden this land for forty years, during which time they shall wander (homeless) on the earth. Do not grieve for these wicked people.' 26
