Like a number of other East Asian languages, Japanese uses a complex system of honorifics, i.e. a system where a number of different levels of politeness are expressed in language via words, word forms or grammatical constructs. These can range from addressing someone or referring to someone with contempt (very informal) to expressing the highest level of reference (as used in addressing or referring to God) or any number of levels in-between.

One way Japanese shows different degree of politeness is through the usage of an honorific construction where the morpheme are (され) is affixed on the verb as shown here in the widely-used Japanese Shinkaiyaku (新改訳) Bible of 2017. This is particularly done with verbs that have God as the agent to show a deep sense of reverence. Here, yakusokus-are-ru (約束される) or “promise” and iw-are-ru (言われる) or “say” are used.

Other uses of honorifics in this verse include:

• The choice of a benefactive construction. Here, mamotte (守って) or “protect” is used in combination with kudasaru (くださる), a respectful form of the benefactive kureru (くれる). A benefactive reflects the good will of the giver or the gratitude of a recipient of the favor. To convey this connotation, English translation needs to employ a phrase such as “for me (my sake)” or “for you (your sake).”
• The choice of a first person singular and plural pronoun (“I” and “we” and its various forms). The most commonly used watashi/watakushi (私) is typically used when the speaker is humble and asking for help. In these verses, where God / Jesus is referring to himself, watashi is also used but instead of the kanji writing system (私) the syllabary hiragana (わたし) is used to distinguish God from others.
• The choice of an imperative construction. In these verses, the honorific form kudasai (ください) reflects that the action is called for as a favor for the sake of the beneficiary. This polite kudasai imperative form is often translated as “please” in English. While English employs pure imperatives in most imperative constructions (“Do this!”), Japanese chooses the polite kudasai (“Do this, please.”).
