Get wisdom, get understanding: forget it not; neither decline from the words of my mouth.
– Proverbs 4:5
Solomon reiterates to get wisdom and to get understanding. It is already clear that acquiring these will cost a price and require continual effort. He also urges constancy to stay the course—forget not, decline not. He exhorts to pay the price to obtain wisdom and not let it go at any offer (Proverbs 23:23).
