1 How lovely is your dwelling place,
O Lord Almighty!
2 My soul yearns, even faints,
for the courts of the Lord;
my heart and my flesh cry out
for the living God.
3 Even the sparrow has found a home,
and the swallow a nest for herself,
where she may have her young—
a place near your altar,
O Lord Almighty, my King and my God.
4 Blessed are those who dwell in your house;
they are ever praising you.
5 Blessed are those whose strength is in you,
who have set their hearts on pilgrimage.
6 As they pass through the Valley of Baca,
they make it a place of springs;
the autumn rains also cover it with pools.
7 They go from strength to strength,
till each appears before God in Zion.
8 Hear my prayer, O Lord God Almighty;
listen to me, O God of Jacob.
9 Look upon our shield, O God;
look with favor on your anointed one.
10 Better is one day in your courts
than a thousand elsewhere;
I would rather be a doorkeeper in the house of my God
than dwell in the tents of the wicked.
11 For the Lord God is a sun and shield;
the Lord bestows favor and honor;
no good thing does he withhold
from those whose walk is blameless.
12 O Lord Almighty,
blessed is the man who trusts in you.
From a commentary that I read... baca means weeping...
By passing through the valley of Baca (a barren land), symbolically we are by our struggles and tears growing strong in His presence. Yes Baca is a barren place, however He revives the hearts of His people, so that for sorrows we will have "rivers of delight."
