     Je fais la promesse de ne plus croire en ce qui me ment / Ne plus me nier dans ma souffrance

     I promise to stop believing in things that deceive me / To no longer deny myself in my suffering

This is one of a fairly large group of irregular -ir verbs that are all conjugated the same way. Other members of this group include sortir and dormir. The most significant difference between these verbs' conjugation and that of the regular -ir verbs is that these verbs' conjugation does not use the infix -iss-. Further, this conjugation has the forms (je, tu) mens and (il) ment in the present indicative and imperative, whereas a regular -ir verb would have *mentis and *mentit (as in the past historic).
