'Mischiefs' in the Bible

For there is no stability in their mouth. Their heart is mischiefs, An open grave is their throat, Their tongue they make smooth.

Thy tongue deviseth mischiefs; like a sharp rasor, working deceitfully.

'Lo, the man who maketh not God his strong place, And trusteth in the abundance of his riches, He is strong in his mischiefs.'

Mischiefs are in its midst. Fraud and deceit depart not from its street.

Which imagine mischiefs in their heart; continually are they gathered together for war.
