Verse 22. The feast of the dedication. Literally, the feast of the renewing, or of the renovation. This feast was instituted by Judas Maccabaeus, in the year 164 B.C. The temple and city were taken by Antiochus Epiphanes in the year 167 B.C. He slew forty thousand inhabitants, and sold forty thousand more as slaves. In addition to this, he sacrificed a sow on the altar of burnt-offerings, and a broth being made of this, he sprinkled it all over the temple. The city and temple were recovered three years afterward by Judas Maccabaeus, and the temple was purified with great pomp and solemnity. The ceremony of purification continued through eight days, during which Judas presented magnificent victims, and celebrated the praise of God with hymns and psalms (Josephus, Ant., b. xii. ch.11). "They decked, also, the forefront of the temple with crowns of gold and with shields, and the gates and chambers they renewed and hanged doors upon them," 1 Mac. iv.52-59. On this account it was called the feast of renovation or dedication. Josephus calls it the feast of lights, because the city was illuminated, as expressive of joy. The feast began on the twenty-fifth day of Chisleu, answering to the fifteenth day of December. The festival continued for eight days, with continued demonstrations of joy.

It was winter. The feast was celebrated in the winter. The word here implies that it was cold and inclement, and it is given as a reason why he walked in Solomon's porch.

Solomon's porch. The porch or covered way on the east of the temple. See Barnes "Mt 21:12".
