LINK: Psalm 104, 114-115
All three of these psalms have been associated with Elijah and Elisha.
This is a wonderful hymn of praise to God for His power, wisdom, and goodness in all of Creation. We do not know who or when it was written, but the statement, "He makes springs pour water into ravines" reminds me of how God provided for Elijah by the Kerith Ravine.
These two psalms are a part of a group of Hallel songs (Psalms 113-118). These songs were sung at the three "great" festivals of Israel, the Passover, Pentecost, and the Feast of Tabernacles, when every male was to come to Jerusalem (Deuteronomy 16:16). They were also sung at other holy days. Psalm 113-114 were sung before the Passover meal, and Psalm 115-118 were sung afterwards.
Psalm 114 recalls the history of God's care for His people in the exodus from Egypt. He provided for every need on their way to the Promised Land just as He provided for Elijah's every need.
Psalm 115 specifically attacks the worship of false gods. So, we can clearly see how it is associated with Elijah and Elisha.
Praise God for His power, wisdom, and goodness in Creation. Then thank Him for His faithfulness throughout your history. Pray through one or all of these Psalms.
