Charles H. Spurgeon on Psalms 123:2

Behold. An ordinary word, but here it hath an extraordinary position. Ordinarily it is a term of attention, used for the awakening of men, to stir up their admiration and audience; but here it is a word not only prefixed for the exciting of men, but of God himself. David is speaking to God in his meditations. "Behold, " saith he. As we take it with respect to God, so it is a precatory particle: he beseeches God to look down upon him, while he looks up unto God: Look on us, as we look to thee; "Behold, Lord, as the eyes of servants, "etc. If we take it as it hath respect to man, so it is an exemplary particle, to stir them up to do the like. "Behold" what we do, and do likewise; let your eyes be like ours. "Behold, as the eyes of servants are to the hand of their masters, so are our eyes to the Lord our God." Let yours have the same fixing. So it is a word that draws all eyes after it to imitation. —Richard Holdsworth.
