Blessed be the name of the Lord
Some prefix the word "saying", as directing to the matter and
manner of praising the Lord, and to express themselves thus; "let
the name of the Lord be blessed"; honoured, glorified, spoken
well of.
From this time forth and for evermore;
from the beginning of time, or as soon as time began, the Lord's
name was to be praised, and was praised by the holy angels, who
were present at laying the foundation of the earth, ( Job
38:4-7 ) , and all the works of the Lord, in their way, have
praised him ever since. Here it may respect the time of penning
this psalm, or the time when the persons called upon commenced
the servants of the Lord, the time of their conversion; a time of
love, life, light, and deliverance, and therefore a time to begin
to praise the Lord: or the whole time of the Gospel dispensation,
to which this psalm refers; the accepted time and day of
salvation, and of the Gentiles glorifying God for his mercy; in
which the Lord is to be and is praised, as he will be to all
eternity, by angels and glorified saints.
