Psalm 124:1-5 (NIV)

1 If the Lord had not been on our side—
    let Israel say—
2 if the Lord had not been on our side
    when people attacked us,
3 they would have swallowed us alive
    when their anger flared against us;
4 the flood would have engulfed us,
    the torrent would have swept over us,
5 the raging waters
    would have swept us away.
