Whoso is wise,.... Or as it may be read interrogatively, "who is wise?" as in Jer 9:12, that is, spiritually wise, wise unto salvation; who is made to know wisdom in the hidden part; for not such as are possessed of natural wisdom, or worldly wise men, much less who are wise to do evil, are here meant.
And will observe these things; the remarkable appearances of divine Providence to persons in distress; the various changes and vicissitudes in the world; the several afflictions of God's people, and their deliverances out of them; the wonderful works of God in nature, providence, and grace; these will be observed, taken notice of, laid up in the mind, and kept by such who are truly wise, who know how to make a right use and proper improvement of them.
Even they shall understand the lovingkindness of the Lord; everyone of the wise men; they will perceive the kindness of God unto all men, in the several dispensations of his providence towards them, and his special love and kindness towards his own people, even in all their afflictions; they will perceive this to be at the bottom of every mercy and blessing; they will understand more of the nature and excellency of it, and know more of the love of God and Christ, which passeth knowledge.
Or "the kindnesses of the Lord shall be understood": that is, by wise men; so R. Moses in Aben Ezra renders the words.
