Yochanan I 2:2-4

Orthodox Jewish Bible

² And he is the kapporah for chattoteinu, not for ours only, but also for the kol HaOlam Hazeh. [VAYIKRA 5:15; YESHAYAH 53:10]

³ And by this we have da’as that we have da’as of Him, if over the mitzvot of Him we are shomer.

⁴ The one making the claim, "I have da’as of Him" and not being shomer over His mitzvot is a shakran (liar) and in this one HaEmes is not.
