Proverbios 25:14

A false gift - שקר מתת mattath shaker , a lying gift, one promised, but never bestowed. "Whoso maketh greate boastes, and giveth nothing;" Coverdale. So the Vulgate : "Vir gloriosus, et promissa non complens ;" "A bragging man, who does not fulfill his promises," is like clouds which appear to be laden with vapor, and like the wind which, though it blow from a rainy quarter, brings no moistness with it. So the vain boaster; he is big with promise, but performs nothing.
