I orginally learned this verse from the NAS. "Let us know...let us press on to know the Lord..." I was surprised to see the NIV "Let us acknowledge the Lord...let us press on to acknowledge the Lord..." Guess the NIRV wins with both though a little less poetic:

(Hosea 6:2-3 NIRV) ^"Let's recognize him as the Lord.
Let's keep trying to really know him.
You can be sure the sun will rise.
And you can be just as sure the Lord will appear.
He will come to renew us like the winter rains.
He will be like the spring rains that water the earth."
