Yahweh uses these questions to scold the people because they feared others rather than him. They didn't even think about him. Alternate translation: "Apparently you really fear others because you have acted deceitfully and you do not rememer me or think about me!" (See: [[rc://en/ta/man/jit/figs-rquestion]])
These two phrases mean basically the same thing and emphasize that, although the people should have remembered Yahweh, they did not. (See: [[rc://en/ta/man/jit/figs-doublet]])
