Psalms 118:27

Shewed us light. As God brought forth light at creation’s morn (see Gen. 1:15), so He will banish the darkness of the night of calamity and reveal the light of His favor.

Sacrifice. Heb. chag, “a festival.” Chag occurs 61 times and is translated “sacrifice” only here and in Ex. 23:18 and Isa. 29:1. The translation is open to question, and many translators prefer to be consistent by rendering chag as “festival” or “feast” in these three instances also. For “cords” (Heb. ‘abothim) some of the ancient versions read, “boughs.” This combination of ideas suggests a highly decorative feast, with boughs decorating the procession or the route of the procession all the way to the “horns of the altar.” There seems to be no satisfactory explanation of the passage if the original translation is retained.
