Psalms 138:4 - Clarke's commentary and critical notes on the Bible

All the kings of the earth shall praise thee, O LORD, when they hear the words of thy mouth. All the kings of the earth - Of the land: all the neighboring nations, seeing what is done for us, and looking in vain to find that any human agency was employed in the work, will immediately see that it was thy hand; and consequently, by confessing that it was thou, will give praise to thy name.
