the hope of eternal life, as founded on Christ and his righteousness, where such that know Wisdom place their hope; and this hope will not make them ashamed; they will not be disappointed, their expectation shall not perish, they will have what they are waiting and hoping for, and what is promised unto them,See Gill on "Pr 23:18".
The Targum is,"which if thou findest, the last shall come better than the first, and thy hope shall not be consumed.'
