  14 H935 When thou art come H776 unto the land H3068 which Jehovah H430 thy God H5414 giveth H3423 thee, and shalt possess H3427 it, and shalt dwell H559 therein, and shalt say, H7760 I will set H4428 a king H1471 over me, like all the nations H5439 that are round about me;
  15 H7760 thou shalt surely H7760 set H4428 him king H3068 over thee, whom Jehovah H430 thy God H977 shall choose: H7130 one from among H251 thy brethren H7760 shalt thou set H4428 king H3201 over thee; thou mayest H5414 not put H5237 a foreigner H251 over thee, who is not thy brother.
