﴿ فَإِن لَّمْ تَأْتُونِى بِهِۦ فَلَا كَيْلَ لَكُمْ عِندِى وَلَا تَقْرَبُونِ ﴾

“But if you do not bring him unto me, you shall never again receive a single measure [of grain] from me, nor shall you [be allowed to] come near me!"”

But if you do not bring him to me there will be no measure that is no provisions for you with me; and do not come near me’ wa-lā taqrabūn is either a prohibition or a supplement to the syntactical locus of fa-lā kayla in other words ‘and you shall be denied the measure and will not be allowed to come near me’.
