True. Morality comes from God because He is the source of all truth and righteousness. Romans 2:15 says God’s law is written on everyone’s heart, so even before Scripture existed, people had a sense of right and wrong given by Him. The Bible doesn’t create morality, it explains, clarifies, and reinforces what God already put in place.

That's why I seem to find predominantly the "excuses" in religion. Yes, they claim morality, but we know (a sense of) morality exists regardless. So, what are you left with then?

The wisdom is doubtful at best, in particular because there is both no consensus and no single way in which these scriptures, regardless of origination, can be interpreted. Wisdom seems to be present in plenty of other places, more thoughtful and rich and respectful. Looking at wisdom and scientific reaearch specifically, there is similar value to be found in arabic cultures without needing to be weighed down by their religious connotation. (Or one's own.)
