7:12
and said,
“Amen! Praise, glory, wisdom, thanks, honor, power, and strength be to our God forever and ever! Amen!”
and said,
This is audibly speaking it, not mentally thinking it. This indicates that worship prayers should be spoken and not just thought.
"Amen!
"Amen!"
The "AMEN!"s bracket the sevenfold doxology. The angels agree entirely with the multitude.
In the original version, each attribute was preceded by "the" (not shown in this translation). This 'the' gives the sense of all or complete. For example, "the power" means all powerful.
The () denotes the order of these attributes as found in Revelation 5:12. There may be some significance to the order; however, this is not clear. This listing goes from "praise words" (praise and glory) to strength words (power and might). The recipient here is GOD (be to our GOD) while in Revelation 5:12, the recipient is Jesus (Worthy is the LAMB).
