Mat 3:15 Suffer it to be so now: for thus it becometh us to fulfil all righteousness.
Let it go now. Because, in this way, being clearly seen, it exists for us. It fulfills all (sprinkling) the requirements of the law.
This are Christ's first words in the Gospels. It includes a play on words and many
The Greek word translated as "suffer," means to let something go or drop, especially in the sense of not caring about it. There is no "it", but in English when we tell someone to "drop it", we add the "it."
"To be so" is not in the Greek text. It is added to create a more complete written sentence from a spoken statement.
The Greek word translated as "now" means "just" or "exactly and "now" in the sense of "just now" when applied to time. Christ usually seems to use it in the sense of "now".
The word translated as "for" introduces a reason or explanation. In today's English, we would usually say,"because," or write "this is because" to prevent run-on sentences.
The word translated in KJV as "thus" is in its adverbial form, so it means "in this manner" or "in this way."
The "it becomes" is from two different verbs, neither of which is the Greek word for "become."
The first verb of "it becomes" means "to be seen clearly" and, from that, "to be conspicuous" and from that "to be conspicuously fitting." However, many Bibles offer it as "fitting" from the most derived definition. This is a rare word for Christ to use, so he is likely he used it for its specific meaning of being seen in an unmistakable way. The word meaning "to be clearly seen" or made conspicuous in some other way (loud, smelly). This is less about what is "fitting" or "proper," that it is about gaining visibility.
The next verb is the Greek word "to be." Translating it as "becometh" is not anything like how it is used in Greek. In English, there is a clear line between the concept of being and the concept of becoming, but it is even clearer in Greek. "Being" is continuing to exist in a current state. "Becoming" is the transition to a new state. There are in many ways complementary opposites in Greek and used that way, especially by Christ. Here, it clearly means "is".
The "us" here is in the form of an indirect object, which has many uses in Greek. Many of those uses work here. It could mean "it is clearly seen..." "...with us" (the instrumental dative), "...in us" (location), "...for us" (benefit), or "of us" (possessive).
The word translated as "to fulfill" means to fill up or complete. Christ uses it in many different ways, but he often uses it in a context like this meaning to complete a prophecy or what was written in scriptures. The form of the word could be a command ("Complete!"), or an infinitive ("to complete") or a simple statement ("it completes").
Next, there is some fun wordplay in the word translated as "all." In this form of the word, it has two different meanings. It is either an adjective, meaning "all" as in "all righteousness" in KJV . However, the same word is also a participle form of the Greek verb meaning "to sprinkle," that is, "sprinkling." One special use of this verb is to describe the sprinkling of healing herbs on a wound. The form is either the subject or object of the noun. Again, however, it lacks an article ("the", "a') which would make its use clear. Of course, if this is a play on words, that would be intentional. In the context of a baptism, which was likely a complete dunking in water, is really quite funny. (The Greek translated as "baptism" in the NT means "to dip" or "to dunk").
The word translated as "righteousness" carries the sense of virtue but specifically that of fulfilling legal or social requirements. This ties it to the idea of fulfilling the law. For Christ, the reference to the written law is implicit in that idea.
For most about the meaning of this verse to us today, see the separate article, Christ's First Words.

"It fulfills," he said, sprinkling it out. "All the requirements of the law."
