What is the suffix ending on the words for iniquities and diseases? (the Kauf,chirriq,yod ending) I see it is interpreted as 'thy' but this is not the usual possessive ending for 'your'. (I am a student with only 1 year study, thank you for your help)
הַסֹּלֵחַ לְכָל־עֲוֹנֵכִי הָרֹפֵא לְכָל־תַּחֲלֻאָֽיְכִי׃
