This is the last in this series of Hallelpsalms (Pss. 113-118). Psalm 136 is also a Hallelpsalm. Psalm 118 describes a festal procession to the temple to praise and sacrifice to the Lord. The subject is God's loyal love for His people. The situation behind it seems to be God's restoring the psalmist after a period of dishonor. This would have been a very appropriate psalm to sing during the Feast of Tabernacles as well as at Passover and Pentecost. The Lord Jesus and His disciples probably sang it together in the Upper Room at the end of the Lord's Supper (cf. Matt. 26:30).
"As the final psalm of the Egyptian Hallel', sung to celebrate the Passover . . ., this psalm my have pictured to those who first sang it the rescue of Israel at the Exodus, and the eventual journey's end at Mount Zion. But it was destined to be fulfilled more perfectly, as the echoes of it on Palm Sunday and in the Passion Week make clear to every reader of the Gospels."193
