Matthew 5:47-48

5:47 And if you only greet your brothers, what more do you do? Even the Gentiles do the same, don’t they? 5:48 So then, be perfect, as your heavenly Father is perfect. ¹ 

[5:48]  ¹ sn This remark echoes the more common OT statements like Lev 19:2 or Deut 18:13: “you must be holy as I am holy.”
