Actually, the first line is “Please lay down your eros.” Based on the next part “cause they're sure to pierce the skin,” I'm sure it's a play on words with “arrows”. It compares the passionate/erotic love “eros,” with the unconditional love of God “agape”. I think the line “and water from a broken well will make you thirst again” sums up this comparison quite well.
