blast

Blast certainly, designates, Deut. 28:42, a voracious insect; the Hebrew çelãçál, “chirping”, suggests that the cricket was possibly meant and might be substituted for blast. In Ps. 127:46 (Hebr., Psa 128:46), blast stands for hãsîl, “the destroyer”, perhaps the locust in its caterpillar state, in which it is most destructive.
