'Suddenly' in the Bible

Let all my enemies be ashamed and greatly horrified;Let them turn back, let them suddenly be ashamed [of what they have done].

Let death come deceitfully upon them;Let them go down alive to Sheol (the nether world, the place of the dead),For evil [of every kind] is in their dwelling and in their hearts, in their midst.

To shoot from ambush at the blameless [one];Suddenly they shoot at him, without fear.

But God will shoot them with an [unexpected] arrow;Suddenly they will be wounded.
