The second paragraph of the shema begins with "and it will come to pass that if you continually hearken to my commandments..."
Apparently shomo-a tishm'u means continually hearken but I would like to know specifically what each of those words means. They both have the same shin mem ayin stem in them, the second one just has a tav thrown on the beginning and a vav tossed on to the end, so they should mean something very similar. Thanks.
