“For He has looked [with loving care] on the humble state of His maidservant;For behold, from now on all generations will count me blessed and happy and favored by God!
In generations past He permitted all the nations to go their own ways;
For from ancient generations [the writing of] Moses has been preached in every city, since he is read aloud in the synagogues every Sabbath.”
which in other generations was not disclosed to mankind, as it has now been revealed to His holy apostles and prophets by the [Holy] Spirit;
to Him be the glory in the church and in Christ Jesus throughout all generations forever and ever. Amen.
that is, the mystery which was hidden [from angels and mankind] for ages and generations, but has now been revealed to His saints (God’s people).
