What does the expression and here in 11th hour he came through mean?

The expression "in the eleventh hour" means at the very last possible moment, right before something is due or something critical is about to happen.

So, "in the eleventh hour he came through" means he arrived or succeeded just in time, when it seemed like it was too late.

Here's a breakdown:

* Eleventh hour: A metaphor referring to the last possible moment, often used in the context of a deadline or a critical situation.

* Came through: To succeed, to fulfill a promise or an obligation, often in a way that was unexpected or difficult.

Example:

"The company was about to go bankrupt, but in the eleventh hour, their biggest investor came through with a large loan that saved them."

In this example, "in the eleventh hour" signifies the critical point just before the company's financial ruin, and "came through" implies that the investor's timely action saved the company.
