Yochanan I 2:3-5

Orthodox Jewish Bible

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.

⁵ But whoever over the dvar of Him is shomer, beemes in this one the ahavas Hashem has been made shleimah. By this we have da’as that in Him we are.
