Note 1 — ISAIAH. (continued 6)
Reading edition
Upon the throne of David. This was in accordance with the promise made to David (1 Kings viii. 25; 2 Sam. vii. 12, 13; Ps. cxxxii. 11). This promise was understood as referring to the Messiah. The primary idea is, that He should be descended in the line of David, and accordingly the New Testament writers are often at pains to show that the Lord Jesus was of that family (Luke ii. 4). When it is said that He would sit upon the throne of David, it is not to be taken literally. The peculiarity of the reign of David was, that he reigned over the people of God. . . . To sit upon the throne of David, therefore, means to reign over the people of God; and in this sense the Messiah sits on his throne.—Barnes.
The angel who came to Mary affirmed these very things of the Son then to be born (Luke i. 32, 33).—Cowles.
