What do the far left numbers mean when I do a show IPtables on an InReach MRV Console Switch?

For example, I did a show IPTables and got the following output:
[1437:67544] -A INPUT -s -d -j ACCEPT
[30:960] -A INPUT -s -d -j ACCEPT
[2:126] -A INPUT -s -d -j ACCEPT
[0:0] -A INPUT -s -d -j ACCEPT

I'm assuming the numbers to the left, between [ ] are hit counts but I need to know if one's in and  ones outbound or what, exactly, they mean.  It's a Linux core, so I'm assuming it's pretty standard.
