3 verses have
yourself
in Edition Clear Qur'an by Talal Itani / Al-Kahf (The Cave)

18:6Perhaps you may destroy yourself with grief, chasing after them, if they do not believe in this information.

18:10When the youths took shelter in the cave, they said, “Our Lord, give us mercy from Yourself, and bless our affair with guidance.”

18:28And content yourself with those who pray to their Lord morning and evening, desiring His Presence. And do not turn your eyes away from them, desiring the glitter of this world. And do not obey him whose heart We have made heedless of Our remembrance—so he follows his own desires—and his priorities are confused.
