Porter Wagoner's you tube attributes Day Of Wrath ( Tell Your Children ) to E.J. and maybelle Carter.

I don't know who wrote this song but I think the Hemhills recorded it.

Blow Ye The Trumpet

Verse: 1
Blow ye the trumpet in Zion,
our Lord is coming back to earth again,
in the holy mountain sound the warning,
for all of those who wear the yoke of sin.

Chorus:
Tell your children and your children's children,
of the second coming of our king,
he will stand upon the Mount of Olives,
Salvation to the dying world to bring.

Verse: 2
Joel prophesied with all his wisdom,
if we failed to walk the righteous path,
it will be too late to ask for mercy,
at the dawning of the day of wrath.

Verse: 3
God gave us his word of revelation,
about our life and how that it should be,
how he planned for us to love and serve him,
he made us to be all that we should be.

I am looking for the lyrics to an old hymn called, I think, Blow Ye Your Horn In Zion. Some of the song goes "Tell your children and your children's children, of the second coming of our King" Another part is "He will stand upon the Mount of Olives, salvation to a dying world.. (He'll bring??) That's about all I can remember other than the words from the title, "Blow ye your horn in Zion".
Thanks!!!
