"Yes, though it costs all your possessions, get understanding" (4:7). Can wisdom be bought?

Here is what the verse says. In Hebrew that half of the verse has no word for costs; it is and with all your qinyan, get understanding. Brown-Driver-Briggs gives qinyan as "thing got or acquired, acquisition", and the verb get, qanah, as "get, acquire" (tap Get). Proverbs has the same verb where the WEB says Buy: "Buy the truth, and don’t sell it" (Proverbs 23:23). With the same verb for buy, it also asks, "Why is there money in the hand of a fool to buy wisdom, since he has no understanding?" (Proverbs 17:16), and it says, "For the LORD gives wisdom" (Proverbs 2:6). So the book says, "though it costs all your possessions, get understanding" (4:7), asks why a fool has money in his hand to buy wisdom (17:16), and says the LORD gives wisdom (2:6). In chapter 4, Get wisdom stands beside "Don’t forget, and don’t deviate from the words of my mouth" (4:5). The chapter doesn't say more about how wisdom is got, and these notes don't either.
