What was the name given to the city of Jebus after David conquered it and built his royal residence?

Was literally just reading about Hezekiah making the underground water tunnel! would love to go! always get the Bible questions right! yup I know my bible very well and I am very proud of it!

Hot chocolate, Yes the Bible described him as being ruddy and handsome in appearance and that he had beautiful eyes! but the short in stature never heard that! well definitely to goliath he was! but the bible doesn't give what is David's height! so I don't really know! how tall he was! probably good height for a man right?!

Would like to go to zion! that is the city of David! love David he is one of my all time fave Bible characters! would love to meet David someday in heaven!!

King David I hear was small in structure but with beautiful features.
