Psalm 130:6 (ESV) … “my soul waits for the Lord more than watchmen for the morning, more than watchmen for the morning.”
In this verse the psalmist expresses both the passion and the perseverance of his desire. Hoping in God’s word, he sets himself to wait upon the Lord. This calls for patience and trust.
In saying that he anticipated the watchmen, he shows by this similitude with what diligence and alacrity he breathed after God. And the repetition is a proof of his perseverance; for there is no doubt that thereby he intended to express an unintermitted continuance of the same course, and consequently perseverance.
Both these qualities in his exercise are worthy of attention; for it is too manifest how slow and cold we are in elevating our minds to God, and also how easily we are shaken and even fall at every little blast of wind. Farther, as the watches of the night were in ancient times usually divided into four parts, this passage may be explained as implying that as the watchmen of the night, who keep watch by turns, are careful in looking when the morning will dawn, so the Prophet looked to God with the greatest attention of mind.
But the more natural sense seems to be, that as in the morning the warders of the gates are more wakeful than all other people, and are the earliest in rising, that they may appear at the posts assigned them, so the mind of the Prophet hastened with all speed to seek God.
The repetition, of this psalm, shows that he stood keeping his gaze perseveringly fixed upon its object.
We must always beware of allowing our fervor to languish through the weariness of delay, should the Lord for any length of time keep us in suspense.[1]
