Matthew Poole and continuators on Psalms 42:3

3. My tears have been my meat , day and night, while they continually say unto me; Where is thy God !

Which notes both the great abundance and constant Course of his Tears, and the secret Satisfaction, and Ease which he found in giving vent to his Passion this way. Possibly his Tears and Grief took away his Appetite, and so were to him instead of Food.

Of whom thou hast so often boasted, as of one so able and ready to help, all that trust in him, and call upon him, and particularly, as one ingaged to thee by many great and special Promises. He is gone and departed from thee, and no where to be found of thee. He is either unable or unwilling to help thee, or regardless of thee.
