lemme have a look
".לב טהור ברא־לי אלהים ורוח נכון חדש בקרבי. אל־תשליכני מלפניך ורוח קדשך אל־תקח ממני"
Create in me a pure heart, O God, and renew a steadfast spirit within me. Do not cast me away from Your presence, and do not take Your holy spirit from me.
רוח קדשך (ru'ach kodshecha) means 'Your spirit of holiness'. In Judaism, this means God’s presence or influence within a person, the divinely granted capacity for moral clarity, wisdom, or inspiration, and it is also tied to prophetic ability (but not in this case). Basically, King David is praying that God doesn't leave him, and that God doesn't remove His guidance.
(For context, King David was in BIG trouble. Dude killed Batsheva's husband and took her for himself. God typically frowns down on that sort of thing.)
This is in Psalm (Tehillim) 51:12-13.
