scp or sftp copy multiple files with single command

I’d like to copy files from/to remote server in different directories.
For example, I want to run these 4 commands at once.

scp remote:A/1.txt local:A/1.txt
scp remote:A/2.txt local:A/2.txt
scp remote:B/1.txt local:B/1.txt
scp remote:C/1.txt local:C/1.txt

What is the easiest way to do that?
