John Gill Commentary Deuteronomy 4:32

"For ask now of the days that are past, which were before thee, since the day that God created man upon the earth, and from the one end of heaven unto the other, whether there hath been [any such thing] as this great thing is, or hath been heard like it?" — Deuteronomy 4:32 (ASV)

For ask now of the days that are past, which were before you ,
&c.] Inquire into and consult the annals of former times, of ages past:

since the day that God created man upon the earth ;
trace them quite up to the creation of the world, and men in it:

and [ask] from the one side of heaven to the other ;
traverse the whole globe, and examine the records of every nation in it in both hemispheres:

whether there has been any such [thing] as this great thing is, or
has been heard like it ?
whether they can give any account of anything seen, heard, or done like what follows; suggesting that they cannot furnish out an instance to be mentioned with it.
