Moses speaking for god forgets

Deuteronomy 5:7 says, “Thou shalt have none other gods before me.

5:8 Thou shalt not make thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the waters beneath the earth:

5:9 Thou shalt not bow down thyself unto them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me,”  Didn’t he just say in Deuteronomy 4:27, “And the LORD shall scatter you among the nations, and ye shall be left few in number among the heathen, whither the LORD shall lead you.

4:28 And there ye shall serve gods, the work of men's hands, wood and stone, which neither see, nor hear, nor eat, nor smell.”  So which is it Merciful (Jealous) god?  Should we or shouldn’t we serve other gods especially since you insist upon calling yourself the only god over and over and over again!
