How to use a function as a row number in Google Sheets [duplicate]

Let's say I want to print the value contained in D7 (Row 7, Column D) into another cell.

I would use =D7.

Great.

But what if I have a function that returns a number, like MATCH, and I want to use that returned number as the row number in my previous example?

I don't know how to do that and where to find that information.

Something like: =D{MATCH("ETH",A:A,1)}

How can I achieve this?
