This is clearly a pendant on its predecessor, and begins where it left off, carrying on the joy and praise.

When deliverance, and especially of an inward sort, is known, joy flows. Jehovah in word and deed is manifest and celebrated. The nations, once dreaded, are nothing before Him. Blessed is the nation whose God is Jehovah, Whose counsel alone stands when theirs is made void. He saw all, when it seemed not. His eye is toward those that feared Him and hoped in His mercy, as the remnant did. He would have His people happy in the knowledge of Himself; and Israel will know Him in displays of power on their behalf here below. We ought to know our God still better, viewing the cross of Christ in the light of His heavenly glory. Compare John 16:9-14.
