“Because you have said, ‘We have cut a covenant with death,
and with Sheol are we in agreement.
When the overflowing scourge passes through,
it will not come to us,
for we have made lies our refuge
and we have hidden ourselves under falsehood.’” Bible other translations

“cut a covenant with death.” The penalty of breaking the Law was death (Rom. 6:23), so these lawbreakers arrogantly brag that that will not happen to them because they have made a covenant with death so that the “scourge” will not come upon them. They were wrong, of course, and died (cp. Isa. 28:18).
