What does Isaiah 51:13 mean?

and hast forgotten Jehovah thy Maker, that stretched forth the heavens, and laid the foundations of the earth; and fearest continually all the day because of the fury of the oppressor, when he maketh ready to destroy? and where is the fury of the oppressor?

And forgettest the Lord thy maker, that hath stretched forth the heavens, and laid the foundations of the earth; and hast feared continually every day because of the fury of the oppressor, as if he were ready to destroy? and where is the fury of the oppressor?

and hast forgotten Jehovah thy Maker, that stretched forth the heavens, and laid the foundations of the earth; and fearest continually all the day because of the fury of the oppressor, when he maketh ready to destroy? and where is the fury of the oppressor?

And you have given no thought to the Lord your Maker, by whom the heavens were stretched out, and the earth placed on its base; and you went all day in fear of the wrath of the cruel one, when he was making ready for your destruction. And where is the wrath of the cruel one?

And thou dost forget Jehovah thy maker, Who is stretching out the heavens, and founding earth, And thou dost fear continually all the day, Because of the fury of the oppressor, As he hath prepared to destroy. And where <FI>is<Fi> the fury of the oppressor?

And thou hast forgotten the Lord thy maker, who stretched out the heavens, and founded the earth: and thou hast been afraid continually all the day at the presence of his fury who afflicted thee, and had prepared himself to destroy thee: where is now the fury of the oppressor?

and forgettest Jehovah thy Maker, who hath stretched out the heavens, and laid the foundations of the earth; and thou art afraid continually all the day because of the fury of the oppressor, when he prepareth to destroy? And where is the fury of the oppressor?
