Deuteronomy 17:15

15. Whom the Lord thy God shall choose The manner in which the divine appointment was to be designated is not stated here. A prophet was the medium of the divine communication in the case of the first king, Saul.

1 Samuel 9:17; 1 Samuel 10:24. Also in the case of David. 1 Samuel 16:12. When Solomon was designated, the choice of the Lord was announced directly to his father David. 1 Chronicles 22:10.

Thou mayest not set a stranger over thee, which is not thy brother The Jews placed great stress upon this prohibition. This is one of the passages of Scripture that were read at the feast of tabernacles in the sabbatical year by the king or high priest. It is related that when King Agrippa came to this passage, while reading the portions of Scripture, tears dropped from his eyes. The people then cried out, to encourage him, “Thou art our brother! Thou art our brother!” BARCLAY’S Talmud, p. 82.
