And he did what was right in the eyes of the LORD and walked in the ways of his father David; he did not turn aside to the right or to the left.
Concerning Josiah we are here told, 1. That he came to the crown when he was very young, only eight years old (yet his infancy did not debar him from his right), and he reigned thirty-one years (Ch2 34:1), a considerable time.
Commenting on 2 Chronicles 34:1-7
And he did [that which was] right in the sight of the LORD, and walked in the ways of David his father, and declined [neither] to the right hand, nor to the left. (a) He followed David in all points that he followed the Lord.
He declined neither to the right hand, nor to the left - He never swerved from God and truth; he never omitted what he knew to be his duty to God and his kingdom; he carried on his reformation with a steady hand; timidity did not prevent him from going far enough; and zeal did not lead him beyond due bounds.
