'Otherwise' in the Bible

Otherwise I should have wrought falsehood against mine own life: for there is no matter hid from the king, and thou thyself wouldest have set thyself against me.

Otherwise it shall come to pass, when my lord the king shall sleep with his fathers, that I and my son Solomon shall be counted offenders.

For a multitude of the people, even many of Ephraim, and Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet did they eat the passover otherwise than it was written. But Hezekiah prayed for them, saying, The good LORD pardon every one

For I said, Hear me, lest otherwise they should rejoice over me: when my foot slippeth, they magnify themselves against me.
