New Defender's Study Bible Notes
13:4 no god but me. There is no true God but the Creator, and there is no Savior but that same Creator. Israel was reminded here—as we should be today—that the only God who is real is both Creator and Savior. No other imagined deity or force of nature can accomplish either creation or salvation.
13:14 power of the grave. This is one of the Old Testament promises of future bodily resurrection. See also Job 19:25-27; Isaiah 26:19; Daniel 12:2; etc.
