In his days shall the righteous flourish - There was nothing but peace and prosperity all the days of Solomon: for, "In his days Judah and Israel dwelt safely; every man under his vine and under his fig-tree, from Dan even to Beersheba;" 1 Kings 4:25.
So long as the moon endureth - ירח בלי עד ad beli yareach, "Till there be no more moon."
In his days shall the righteous flourish - It will be a period when just and upright people will be protected, or when they shall receive the countenance of him who reigns. The administration of the kingdom that is to be set up will be in favor of righteousness or justice. The word “flourish” here is derived from the growth of plants - as plants sprout, or spring up - an emblem of prosperity.
And abundance of peace - literally, “multitude of peace;” that is, The things which produce peace, or which indicate peace, will not be few, but numerous; they will abound everywhere. They will be found in towns and villages, and private dwellings; in the calm and just administration of the affairs of the State; in abundant harvests; in intelligence, in education, and in undisturbed industry; in the protection extended to the rights of all.
So long as the moon endureth - Margin, as in Hebrew, “until there be no moon.” That is, until the moon shall cease to shine upon the earth. See Psalm 72:5.
“I have sworn unto David My servant ... with whom My hand shall be established: Mine arm also shall strengthen him.... My faithfulness and My mercy shall be with him: and in My name shall his horn be exalted. I will set his hand also in the sea, and his right hand in the rivers. He shall cry unto Me, Thou art my Father, my God, and the Rock of my salvation. Also I will make him My first-born, higher than the kings of the earth. My mercy will I keep for him forevermore, and My covenant shall stand fast with him.” Psalm 89:3-28. PP 755.1
“His seed also will I make to endure forever,
And his throne as the days of heaven.” Psalm 89:29. PP 755.2
“He shall judge the poor of the people,
He shall save the children of the needy,
And shall break in pieces the oppressor.
They shall fear thee while the sun endureth,
And so long as the moon, throughout all generations....
In his days shall the righteous flourish;
And abundance of peace, till the moon be no more.
He shall have dominion also from sea to sea,
And from the river unto the ends of the earth.”
“His name shall endure forever:
His name shall be continued as long as the sun:
And men shall be blessed in him:
All nations shall call him blessed.” PP 755.3
