To make thine enemies thy footstool", as in Psalm 110:1, signifies to subjugate and keep under the hells. Here a footstool signifies the lowest region under the heavens -- that is to say, the hells. A footstool, as in Psalm 132:7, signifies the Lord's church in the earths.

As with many common verbs, the meaning of “to say” in the Bible is highly dependent on context. Who is speaking? Who is hearing? What is it about? Is it a command, a message, an apology, instruction? All these things enter into the meaning of “say.” In general, though, “saying” has to do with sharing truth at various levels -- from the most exalted power people can have to perceive the Lord's desires directly to the most basic of orders issued to people at their lowest.
