For thy mercy is great unto the heavens
and thy truth unto the clouds.
Basically what he's saying is that God's mercy
and his truth reaches to those heights.
That's what the Bible is saying there when it says,
thy mercy is great unto the heavens.
Meaning that basically it stretches to the heavens.
That's how high it is.
So basically the poetry here is to look up at the sky,
which is obviously the highest thing that there is.
There's nothing higher than the sky
because once you go beyond the sky,
things aren't really high anymore
because there's no reference point.
You're just out in space at some point, right?
The highest thing in relation to the earth
where you can still talk about height
or think about height is the heavens, right?
The sky.
And so it's just talking about God's mercy
being great unto the heavens.
