The 110th Psalm’s structure is anchored within two prophetic pronouncements (vs. 1 and 4). Though scholars have espoused various structural breakdowns, a two section division seems most sensible. Parallelisms between verses 1-2 and 4-5 are too numerous to ignore. These include the repetition of the name hwhy and repetition of His acts of pronouncing a future reality.
The entire psalm is a particularization of the phrase “until I make your enemies a footstool for your feet (^yl,(g>r:l. ~doåh] ^yb,ªy>ao÷ tyviîa’-d[;).” This particularization occurs by means of numerous contrasts: hands and feet; sitting and moving; Zion and the nations; my right hand and your right hand.
The first pronouncement proclaims that the king will sit on Yahweh’s right hand until the time at which his enemies become a footstool for him. As noted, this idea is then particularized in the four subsections that follow, essentially announcing “how” hwhy will bring this reality about. The second pronouncement (vs. 4) connects the king with the priestly lineage of Melchizedek, a feature which might seem out of place if we were discussing Aaronic priests, but because Melchizedek’s Genesis context is being blessed by Abraham after the defeat of the kings of Sodom, the psalmist’s connecting him to military imagery seems natural. This pronouncement is, like the first, accompanied by four subsections which serve to particularize verse 4.
Finally, one of the more interesting features of the psalm involves a stylistic connection, at points, with prophetic oracles. Each of the two statements anchoring the structure of the psalm stylistically reflects prophetic discourse. Examples of prophetic discourse and the importance of the structure of this psalm will be discussed in the following post in this series.
 There are also other occurrences which indicate this two fold division, namely the repeated use of certain elements in the one section with no reference to the element in the other section. For example, Allen astutely notes the first strophe is characterized by the eightfold repetition of the pronominal suffix ^ (your) in vs. 1-3, while the second is marked by the fourfold repetition of the preposition l[;. Neither of these elements occur with the same frequency in the alternative strophe.
 Other notable features involve an inclusion that moves from the first verse with there reference to the kings enemies being placed under his feet (lg<r,) to the final verse which references his head (varo,) being lifted up. The alliterative aspect of this inclusion highlights another prominent feature of this psalm.
 One example will suffice here. The “Day of Wrath” rhetoric occurs in numerous prophetic books. It is a day in which Yahweh is viewed as a divine warrior warring against pagan nations and intervening to protect the king and His people. Is. 5:15, Jer. 9:21, Ez. 32:5-6
