Psalms 42:7

7.Depth calleth unto depth These words express the grievousness, as well as the number and long continuance, of the miseries which he suffered; as if he had said, I am oppressed not only with one kind of misery, but various kinds of distress return one after another, so that there seems to be neither end nor measure to them. In the first place, by the term depth, he shows that the temptations by which he was assailed were such, that they might well be compared to gulfs in the sea; then he complains of their long continuance, which he describes by the very appropriate figure, that his temptations cry out from a distance, and call to one another. In the second part of the verse, he continues the same metaphor, when he says, that all the waves and floods of God have passed over his head By this he means that he had been overwhelmed, and as it were swallowed up by the accumulation of afflictions. It ought, however, to be observed, that he designates the cruelty of Saul, and his other enemies, floods of God, that in all our adversities we may always remember to humble ourselves under the mighty hand of God which afflicts us. But it is of importance to go beyond this, and to consider, that if it should please God to rain with violence upon us, as soon as he shall have opened his sluices or waterspouts, there will be no termination to our miseries till he is appeased; for he has in his power means marvellous and unknown for executing his vengeance against us. Thus, when once his anger is kindled against us, there will be not only one depth to swallow us up, but depth will call unto depth. And as the insensibility of men is such, that they do not stand in awe of the threatenings of God, to the degree in which they ought, whenever mention is made of his vengeance, let us recall this verse to our recollection.
