Matthew 5:28

5:28 But I say to you that whoever looks at a woman to desire her has already committed adultery with her in his heart.

Matthew 13:17

13:17 For I tell you the truth, ¹  many prophets and righteous people longed to see ²  what you see but did not see it, and to hear what you hear but did not hear it.

[13:17]  ¹ tn Grk “truly (ἀμήν, amhn) I say to you.”

[13:17]  ² sn This is what past prophets and righteous people had wanted very much to see, yet the fulfillment had come to the disciples. This remark is like 1 Pet 1:10-12 or Heb 1:1-2.
