Mat 24:23 Then if any man shall say unto you, Lo, here [is] Christ, or there; believe [it] not.
Mat 24:24 For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if [it were] possible, they shall deceive the very elect.

The point here is that during times of great pressure, people will look for saviors to help them. This demand will create supply. People will rise claiming to be saviors and prophets. People looking for signs and wonders will find them.

"Shall show" is from didômi, which means "to give freely," "to be ready to offer," "to hand over," "to assign," "to grant," "to offer," "to deliver up," and "to give oneself."

"Wonders" is from teras, which means "sign," "wonder," "marvel," "portent," and "monstrosity."

"Elect" is from eklektos, which means "picked out" and "selected."
