But  -- The word translated as "nevertheless" is a less common preposition used like a conjunction that means "except," "save," with an object in the form usually translated as "possessive," or "besides," and "in addition to" without. This is not the word usually translated as "but."

love -- (CW) The word translated as "love" expresses a lot of different ideas including "to be fond of," "to greet with affection," "to persuade," and "to be contented with." Jesus however, applies it to relationships where we have a duty to care for others: family, God, etc. Another word, also translated as "love," is used to for relationships of affectionate friendship that are more voluntary. To distinguish this word, translating it as "cares for" seems to work best. See this article on love for more information.

ye -- This is from the second-person, plural form of the verb.

your -- The word translated as "your" is a plural, second-person pronoun in the genitive case. This pronoun follows the noun so the possessive "of yours." Here, it is the object of the previous preposition.

missing "the/this"  -- (MW) The untranslated word is the Greek definite article," the," which usually precedes a noun and, without a noun, takes the meaning of "the one."

enemies, -- The word translated as "foes" primarily means "hated," "hater,"  "hateful," and "hating." It is an adjective used as a noun. The use of this word is very specific in Greek literature. It describes one who was a friend, but who has been alienated and refuses to be reconciled. It is from a rare Greek word meaning "hate," but it is not from the Greek word that Jesus uses for hate. It is usually translated as "enemy" in the KJV.  However, from Jesus's point of view "the enemy" seems to be "hating" others.

children -- (CW) The word translated as "children" is the Greek word for "son," "scion," or "descendant." Like most male words, it can be used as a generic term for both sexes when they are descendants of someone When it refers to "sons" specifically, it should be translated that way, but when it can be applied to anything, the less familiar "descendant" is better than the more generic "children," especially since this word can refer to adults. It can refer to all offspring in later generations, just like "father" refers to all previous generations. Jesus also used it metaphorically to describe those who follow a way of thought or set of beliefs that descend from an individual. More about it in this article.
