Observe

Psalms 107:43 KJV
Whoso is wise, and will observe these things, even they shall understand the lovingkindness of the LORD.

A wise person, one who understands the lovingkindness of the Lord, is the person who observes those things God does. The Psalm is a litany of the works of God
How He redeems His people from the hand of the enemy vs 2
How He gathers His people from the four corners of the world vs 3
How He delivered them out of their distresses vs 6
How He leads them to His habitation vs 7
How He satisfies the longing soul vs 9
How He binds those in affliction who rebel against His words vs 10-11
How He saves them who cry in their distresses vs 13
How He commands the stormy winds vs 25
How He turns rivers into wilderness vs 33
How He turns the wilderness into standing water vs 35
How He blesses those who are multiplied greatly vs 38
How He brings low those who are oppressed and afflicted vs 39
How He pours contempt upon the princes vs 40 and
How He sets the poor on high vs 41
As we study these things we are warned
As we study these things we are urged to cry on the Lord
As we study these things we come to know the power of God

The wise man will observe and study them and
Then that wise man will come to know the love and kindness of the Lord
