'Moment' in the Bible

But we, brethren, having been bereaved of you and separated for a little moment in person, not in heart, have used more abundant diligence to see your face with much desire;

While they are saying, “Peace and safety [all is well and secure!]” then [in a moment unforeseen] destruction will come upon them suddenly like labor pains on a woman with child, and they will absolutely not escape [for there will be no way to escape the judgment of the Lord].
