2 verses have
swear
in Edition Clear Qur'an by Talal Itani / Al-Mujaadila (The Pleading Woman)

58:14Have you considered those who befriended a people with whom God has become angry? They are not of you, nor of them. And they swear to a lie while they know.

58:18On the Day when God will resurrect them altogether—they will swear to Him, as they swear to you, thinking that they are upon something. Indeed, they themselves are the liars.
