I have generally heard this as a round, with both English and Hebrew words. The two common English verses, singable with the Hebrew, are:

And every man 'neath his vine and fig tree. Shall live in peace and unafraid.

And into plowshares beat their swords, Nations shall learn war no more.

The second verse is the Lo yisa goy part and the other transliterated verse may be the first one...but my Hebrew isn't good enough to say for sure.
