“For all this I considered in my heart even to declare all this, that the righteous, and the wise, and their works, are in the hand of God: no man knoweth either love or hatred by all that is before them. I considered: Heb. I gave, or, set to my heart”
Meaning, what things he ought to choose or refuse: or man knoweth not by these outward things, that is, by prosperity or adversity, whom God doth favor or hate, for he sendeth them as well to the wicked as to the godly.
