I heard that the root of the word, "Blessed" is macro. So when one reads "Blessed" it is equivalent to saying "expanded and filled."
[Expanded and filled] are those who dwell in your house...they are every praising you.
[Expanded and filled] are those whose strength is in God...who have their hearts set on pilgrimage.
As they pass through the Valley of Baca, [they are stretched]. And yet, they make it a place of springs.
(i.e. the redemptive nature of the tears that come from weeping.)
Oh that our valleys would expand us. God's mercy in the midst is not just to expand us - but to also fill us.
