David had to watch his step in Gath, not only in what he did but also what he said, because he was a man under suspicion and was being watched. He had a target on his back and only the Lord could protect him. David chose Gath because he thought it was the last place Saul would expect to find him, but when he made that choice, he was walking by sight and not by faith. Faith is living without scheming. David prayed that God would judge Israel’s enemies.
In verses 8–9, David reminded the Lord of the sufferings he had endured in exile, and then suggested that these sufferings qualified him to have his prayers answered and his enemies defeated. That would assure David that God is behind his cause (Rom. 8:31–39). God knew about David’s wanderings and numbered them (121:8), and He had preserved his tears as well (see 2 Kings 20:1–6). God listed his tears on His scroll (v. 8 niv), or put them in His bottle or wineskin (kjv, nasb). Archaeologists have unearthed small “tear bottles” in which mourners collected their tears and then deposited the bottle at the gravesite. The point is simply that God is aware of what we feel and how we suffer, and His records are accurate (69:28; 87:6; 130:3; 139:16; Ex. 32:32; Neh. 13:14; Ezek. 13:9; Dan. 7:10; Mal. 3:16; Rev. 20:12; 21:27). David repeated the refrain in verses 10–11, but he used the covenant name “Jehovah” this time.
