Thomas Aquinas, on Ps 49:22

“Understand these things, you that forget God; lest he snatch you away, and there be none to deliver you.”

“"Understand these things, you who forget God." Here he exhorts sinners to consideration. And first, to considering the severity of God. Second, he shows what is acceptable to God in sacrifices. First, therefore, he exhorts to understanding. Hence he says, "Understand these things, you who forget God," namely, consider the things that have been said. And this is necessary, because you have forgotten God. Dt. 32: "You have forgotten God your creator." Second, what he means by "understand": "Lest he seize you," namely the Devil, "and there be no one to deliver," namely from his power. When the Devil seizes for the punishment of Hell, there is no one who delivers. Sometimes he seizes unto sin, and God delivers the sinner. Ps. 90: "He shall deliver him." That he does not deliver from the power of the Devil unto punishment is not from impotence, but from his justice he does not will it.”
