I love the King James Version.

In Psalm 78:65 & 66, God wakes up like a drunk from his stupor,
then proceeds to kick ass:

Then the Lord awaked as one out of sleep,
and like a mighty man that shouteth by reason of wine.

And he smote his enemies in the hinder parts:
he put them to a perpetual reproach.

אָחוֹר (a.chor) back

Meaning:

1) the back side, the rear
1a) backwards
1b) hereafter (of time)
1c) behind
