1 Pedro 4:8

And above all things have fervent charity among yourselves. — The original is far more vigorous: But before all things keeping intense your charity towards yourselves. St. Peter assumes that the charity is there, but insists on its not being suffered to flag in outward expression. (Comp. the same word in 1 Pedro 1:22; also in Lucas 22:44; Atos 12:5; Atos 26:7.)

Shall cover. — Properly, neither “shall” nor “will,” the right reading being present, covereth. The words are usually said to be a quotation from Provérbios 10:12, “Hatred stirreth up strifes, but love covereth all sins;” but they are widely different from the LXX. in that passage, and also vary from the Hebrew; and as precisely the same variation occurs in Tiago 5:20, it seems more probable either that St. Peter had the passage of St. James consciously in his mind, or that the proverb was current and familiar to both writers in the form, “Love covereth a multitude of sins.” It is, therefore, unsafe to argue from the exact shade of meaning which the words bear in Provérbios 10:12. To “cover,” in Hebrew, often means to “forgive,” the idea being that of an offensive object which you bury or hide by putting something else over it; see, for examples, Salmos 32:1; Salmos 85:2; and the place in Proverbs seems to mean that whereas a bitter enemy will rake up every old grudge again and again, one who loves will not allow even himself to see the wrongs done to him by a friend. If this sense be accepted here, it will imply that the Christians in Asia had a good deal to put up with from each other; but even so, the argument seems a little strained: “Keep your charity at its full stretch, because charity forgives, however many the wrongs may be.” It far better suits the context to take the proverb in the same sense as in St. James, without any reference to the Old Testament passage. In St. James it is usually taken to mean, “He shall save (the convert’s) soul from death, and shall cover (i.e., procure for him the pardon of) a multitude of sins;” but as the true reading there is “his soul,” it is more natural to suppose that St. James is holding up, as the reward of converting the sinner, that the person who does so shall save his own soul, and procure for himself the pardon of a multitude of sins. So here it seems obvious that St. Peter is urging charity as something which will be found advantageous when the “end of all things” comes; and the advantage he mentions is, “because charity covereth a multitude of sins:” i.e., the exercise of this grace makes up for a great many other shortcomings in the man. A very good case might be made out for a doctrine of Justification by Love.
