But Mary kept all these things, and pondered them in her heart.

People's New Testament

2:19 Mary kept all these things. A mother forgets none of those things which occur respecting her children.

Matthew Henry's Concise Commentary

2:8-20 Angels were heralds of the new-born Saviour, but they were only sent to some poor, humble, pious, industrious shepherds, who were in the business of their calling, keeping watch over their flock. We are not out of the way of Divine visits, when we are employed in an honest calling, and abide with God in it. Let God have the honour of this work; Glory to God in the highest. God's good-will to men, manifested in sending the Messiah, redounds to his praise. Other works of God are for his glory, but the redemption of the world is for his glory in the highest. God's goodwill in sending the Messiah, brought peace into this lower world. Peace is here put for all that good which flows to us from Christ's taking our nature upon him. This is a faithful saying, attested by an innumerable company of angels, and well worthy of all acceptation, That the good-will of God toward men, is glory to God in the highest, and peace on the earth. The shepherds lost no time, but came with haste to the place. They were satisfied, and made known abroad concerning this child, that he was the Saviour, even Christ the Lord. Mary carefully observed and thought upon all these things, which were so suited to enliven her holy affections. We should be more delivered from errors in judgment and practice, did we more fully ponder these things in our hearts. It is still proclaimed in our ears that to us is born a Saviour, Christ the Lord. These should be glad tidings to all.
