'Didst' in the Bible

Was Jehovah wrathful with the rivers? Was thine anger against the rivers? Was thy rage against the sea, That thou didst ride upon thy horses, Thy chariots of salvation?

Thy bow was made naked, The rods of discipline sworn according to thy word. Selah. Thou didst cleave the earth with rivers.

Thou didst march through the land in indignation, Thou didst thresh the nations in anger.

Thou wentest forth for the salvation of thy people, For the salvation of thine anointed; Thou didst smite off the head from the house of the wicked, Laying bare the foundation even to the neck. Selah.

Thou didst strike through with his own spears the head of his leaders: They came out as a whirlwind to scatter me, Whose exulting was as to devour the afflicted secretly.

Thou didst walk through the sea with thy horses, The heap of great waters.
