'Groaning' in the Bible

"And now, Son of Man, you are to start groaning until you're sick to your stomach. You are to groan bitterly right in front of them.

When they'll ask you, "Why are you groaning?' you are to say, "Because of the news that just arrived. Every heart will melt with fear, every hand will grow limp, every spirit will grow faint, and every knee will glisten with sweat.' Look! It has come and it will be fulfilled," declares the Lord GOD.
