Psalm 89:1-4

^I “Maskil” = maskiyl. 13x in OT. From sakal (to consider or be prudent; to instruct, be an expert; dealing prudently, which implies success and prospering; can mean laying cross-wise). This is maskil or maschil. It is a poem used for instruction.
^II “Ethan” = Ethan. 8x in OT. From the same as ethan (root might mean to continue; mighty, strong, ever-flowing, enduring, or permanence). This is Ethan, a name meaning “permanence” or “permanent” or “perpetuity” or “perennial” or “firmness.” See https://www.abarim-publications.com/Meaning/Ethan.html
^III “Ezrahite” = Ezrachi. 3x n OT. From zarach (to rise, shine, or dawn; can also describe symptoms of leprosy). This is Ezrahite, one whose ancestor is Zerah. It may mean “born of the native” or “son of dawn” or “sprung up” or “of the family of Zerah.” See https://www.abarim-publications.com/Meaning/Ezrahite.html

^IV “steadfast love” = chesed. From chasad (being good, kind, merciful; may mean bowing one’s neck as is done in the presence of an equal for courtesy’s sake; so, if one in a superior position is treating you like an equal, that is what is captured here). This is favor, goodness, kindness, loving kindness, pity, reproach, or a good deed. When done by God to humanity, this is mercy/loving kindness. When done by humanity to God, it is piety.
^V “Lord” = YHVH. From havah (to be, become) or hayah (to come to pass, become, be). This is the name of the God of Israel, the self-existent and eternal one, the tetragrammaton. This pronunciation has been lost to time so “Lord” is generally used in its place.
^VI “forever” = olam. This is a long scope of time whether in the past (antiquity, ancient time) or in the future (eternal, everlasting).

^VII “mouth” = peh. This is mouth in a literal or figurative sense. So, more literally, it can be beak or jaws. More figuratively, it refers to speech, commands, or promises.
^VIII “proclaim” = yada. This is to know, acknowledge, advise, answer, be aware, be acquainted with. Properly, this is to figure something out by seeing. It includes ideas of observation, recognition, and care about something. It can be used causatively for instruction, designation, and punishment.
^IX “faithfulness” = emunah. From aman (to believe, endure, fulfill, confirm, support, be faithful, put one’s trust in, be steadfast. Figuratively, this is to be firm, steadfast, or faithful, trusting, believing, being permanent, morally solid). This word is literally firmness, but figuratively fidelity, faithfulness, honesty, responsibility, trust, truth, steadfastness. This word shares a root with the word “Amen.”
^X “to all generations” = dor + dor. Literally, “from generation and generation.” From dur (to move in a circle, which implies living somewhere or remaining there; it can also be the sense of piling or heaping up). This is a revolution of time, which is to say, an age or generation. It can also be a dwelling or one’s posterity.

^XI “established” = banah. This is to build, make, set up, restore, repair, or obtain children. It is to build literally or figuratively.
^XII “is as firm” = kun. Properly, this means in a perpendicular position. So, it is set up in a literal sense – establish, fix, fasten, prepare. In a figurative sense, it is certainty, to be firm, faithfulness, render sure or prosperous.
^XIII “heavens” = shamayim. Root may mean being lofty. This is sky, the air, or heaven. It is in a dual noun form so this might refer to the part of the sky where the clouds move on the one hand and the part beyond that where the sun, moon, and stars are on the other hand.

^XIV “made” = karat. This is to cut down, cut off, or make a covenant (idiom for making a covenant is “to cut a covenant”). It can also mean to destroy, fail, or consume.
^XV “covenant” = berit. Perhaps from barah (to eat, choose, make clear); perhaps from bar (grain, wheat); from bara (to select, purify, cleanse, test, brighten, polish). This is a compact, covenant, alliance, treaty, or league.
^XVI “chosen” = bachir. From bachar (to choose, appoint, try, excellent). This is chosen or choice. So, it implies excellence.

^XVII “sworn” = shaba. Perhaps from sheba (seven – the number of perfection/sacred fullness). This is to swear, curse, vow, make a covenant. Properly, it can mean to be complete. This is to seven oneself – as in affirming something so strongly it is as though it were said seven times.
^XVIII “servant” = ebed. From abad (to work, serve, compel; any kind of work; used causatively, can mean to enslave or keep in bondage). This is a servant, slave, or bondservant.
^XIX “David” = David. From the same as dod (beloved, love, uncle); the root may mean to boil, which is used figuratively to describe love. So, this implies someone you love such as a friend, a lover, or a close family member like an uncle. David’s name likely means something like “beloved one.”

^XX “establish” = kun. Same as “is as firm” in v2. See note XII above.
^XXI “descendants” = zera. From zara (to sow or scatter seed; conceive or yield). This is seed or sowing. It can, thus, mean a fruit, plant, sowing time, child, offspring, or posterity.
^XXII “forever” = ad + olam. Literally, “even to forever.” Olam is the same as “forever” in v1. See note VI above.
^XXIII “build” = banah. Same as “established” in v2. See note XI above.
^XXIV “throne” = kisse. From the same as kese (full moon); perhaps from kasah (to cover, conceal, overwhelm; to cover as clothes do or to hide a secret). This is throne – a seat that is covered or has a canopy. Thus, it is a seat that conveys authority.
^XXV “Selah” = selah. From salal (to lift up, build, pile, extol, exalt; can also be used for opposing as a dam holds back water). This is to lift up or exalt. Also, “selah” in the psalms where its precise meaning is uncertain. It could be a pause in the music, a moment of silence. It could signal a change in the service or mean something akin to amen.
