How difficult it is to guess the reasons for someone's actions is compared to how hard it is to see the bottem of a deep lake or river. (See: [[rc://en/ta/man/translate/figs-simile]])

## will draw them out ##

AT: "will cause the purposes to be known" or "will figure it out"

## loyal ##

"faithful" or "trustworthy"

## but who can find one who is faithful? ##

The implicit answer is "few can find someone like that" AT: "but few men can find a person who is faithful" or "but it is hard to find a person who really is faithful" (See: [[rc://en/ta/man/translate/figs-rquestion]])
