Psalm 37:16-18

^A “better” = tob. From tob (to be pleasing, to be good). This is good, beautiful, pleasant, agreeable, bountiful, at ease. This word is used for goodness as a concept, a good thing, a good person. This can refer to prosperity and welfare as well as joy, kindness, sweetness, and graciousness. So, this is ethically good, but also enjoyably good.
^B “little” = me’at. From ma’at (being or becoming small, decrease, diminish, pare off). This is a little or few, lightly little while, very small matter.
^C “righteous person” = tsaddiq. From the same as tsedeq (rightness, righteousness, just cause, vindication; that which is right in a natural, moral, or legal sense; abstractly equity; figuratively prosperity). This is just, innocent, righteous, righteous one, or lawful.

^D “abundance” = hamon. From hamah (to growl, cry out, be moved, murmur, hum, mourn, rage, clamor). This is a sound, noise, roar, rumbling, wealth, crowd, disquietude.
^E “many” = rab. From rabab (increasing in any aspect whether quantity, authority, size, quality, greatness, etc.). This is abundance, many, elder, exceedingly, great. It refers to abundance of amount, rank, or status.
^F “wicked” = rasha. This is morally wrong so it refers to someone who is actively bad as wicked, criminal, an evil person, offender, condemned, or ungodly.

^G “arms” = zeroa. Perhaps from zara (to sow, scatter seed, conceive). This is the arm, shoulder, or foreleg of an animal. It is figuratively used for power, force, might, or help.
^H “broken” = shabar. This is break, collapse, destroy, break in pieces, tear. It is bursting in a literal or figurative sense.
^I “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.
^J “upholds” = samak. This is to lean, rest, support, brace, uphold, sustain, or establish. It is to lean on in a positive or negative sense.

^K “knows” = 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.
^L “days” = yom. Root may mean being hot. This is the day in a literal or figurative sense. It can also mean birth, age, daylight, continually or other references to time.
^M “blameless” = tamim. From tamam (to finish or accomplish; to make perfect, demonstrate that you are upright; consume; to complete in a literal or figurative sense). This is entire in a literal or figurative sense. So, it could be complete, full, intact, or without defect. Alternately, it could refer to being sound, having integrity, being sincere or perfect.

^N “heritage” = nachalah. Related to nachal (to inherit, occupy, distribute, take as heritage). This is properly something that was inherited. It can mean occupancy generally or, more particularly, an heirloom or an estate. This can be an inheritance, gift, possession, or portion.
^O “abide” = hayah. Related to “Lord” in v17. See note I above.
^P “forever” = olam. This is a long scope of time whether in the past (antiquity, ancient time) or in the future (eternal, everlasting).
