Word to your moms, I came to drop bombs
I got more rhymes than the Bible's got Psalms
Rappers are not generally known for their humility, instead very often wishing to convey the message that they are magnificent and therefore not to be trifled with. "Jump Around", despite its shiny, bouncy package, is true to form, filled as it is with the requisite orders, boasts, and threats that you rarely find in other music genres. Within this context, having more rhymes than there are Psalms is a rather modest claim, as there are only 150 of them.
A charitable explanation is that House of Pain decided that it's a good rhyme, pedants be damned. But it still leaves the impression that someone might have thought "The Bible is long, it must have a whole ox-load of Psalms". Regardless, 150 turned out to be more rhymes than they needed anyway; "Jump Around" was the first and last hurrah for the whole Irish-American rap genre. Sadly, that genre's death means that today we're missing out on movies that are a frighteningly awesome blend of Stomp The Yard and Riverdance.
