Albert Barnes Commentary Matthew 2:9-10

"And they, having heard the king, went their way; and lo, the star, which they saw in the east, went before them, till it came and stood over where the young child was. And when they saw the star, they rejoiced with exceeding great joy." — Matthew 2:9-10 (ASV)

The star—went before them. From this it appears that the star was a luminous meteor, perhaps not far from the ground.

It is not unlikely that they lost sight of the star after they began their journey from the East. It is probable that it first appeared to them in the direction of Jerusalem. They concluded that the expected King had been born and immediately began their journey to Jerusalem.

When they arrived there, it was important that they should be directed to the very place where he was, and the star appeared again. It was for this reason that they rejoiced. They felt assured that they were under heavenly guidance and would be conducted to the newborn King of the Jews. And this shows:

1. That the birth of Jesus was an event of great moment, worthy of the Divine direction of these men to find the place of his birth.
2. God will guide those who are willing to find the Saviour. Even if for a time the light should be withdrawn, it will appear again and direct us in the way to the Redeemer.
3. Direction to Christ should fill us with joy. He is the way, the truth, and the life; the Saviour, the Friend, the all in all. There is no other way of life, and there is no peace to the soul until he is found. When we are guided to him, therefore, our hearts should overflow with joy and praise; and we should humbly and thankfully follow every direction that leads to the Son of God (John 12:35–36).
