'Realized' in the Bible

I realized that wisdom has an advantage over folly, just as light has an advantage over darkness.

{The wise man can see where he is walking}, but the fool walks in darkness. Yet I also realized that both of them suffer the same fate.

There is nothing better for a person than to eat and drink and {find delight} in his toil. For I also realized that this [is] from the hand of God!

So I realized that there is {nothing better} for them than to {rejoice and enjoy themselves} during their lives.

I also realized that all [of the] toil and all [of] the skillful work that is done--it [is] envy between one man and {another}. This also [is] vanity and chasing wind!
