God is the LORD, which hath shewed us light: bind the sacrifice with cords, even unto the horns of the altar. God is the Lord - Rather אל יהוה El Yehovah, the strong God Jehovah.
Which hath showed us light - ויאר לנו vaiyaer lanu, "And he will illuminate us." Perhaps at this time a Divine splendor shone upon the whole procession; a proof of God's approbation.
Bind the sacrifice with cords - The Chaldee paraphrases this verse thus: "Samuel the prophet said, Bind the little one with chains for a solemn sacrifice, until ye have sacrificed him and sprinkled his blood on the horns of the altar." It is supposed that the words refer to the feast of tabernacles, and חג chag here means the festival victim. Several translate the original "keep the festival with thick boughs of the horns of the altar." In this sense the Vulgate and Septuagint understood the passage. David in this entry into the temple was a type of our blessed Lord, who made a similar entry, as related Matthew 21:8-10.
