'Ourselves' in the Bible

Because ye have said, We have made a covenant with death, and with Sheol are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us; for we have made lies our refuge, and under falsehood have we hid ourselves:

Come ye,'say they , I will fetch wine, and we will fill ourselves with strong drink; and to-morrow shall be as this day, a day great beyond measure.
