• Huastec: “a broken-off word” (“based on the concept of ‘breaking off a word’ and leaving it with the person with whom an agreement has been reached”)
• Tetelcingo Nahuatl: “a death command” (i.e. “a special term for testament”)
• Piro: “a promised word”
• Eastern Krahn: “a word between”

• Tagbanwa: “initiated-agreement” (source: Tagbanwa Back Translation)
• Guhu-Samane: “The concept [in Mark 14:24 and Matthew 16:28] is not easy, but the ritual freeing of a fruit and nut preserve does afford some reference. Thus, ‘As they were drinking he said to them, ‘On behalf of many this poro provision [poro is the traditional religion] of my blood is released.’ (…) God is here seen as the great benefactor and man the grateful recipient.” (Source: Ernest Richert in The Bible Translator, 1965, p. 81ff. )
• Chichewa: pangano. This word can also be translated as a contract, agreement, or a treaty between two parties. In Chewa culture, two people or groups enter into an agreement to help each other in times of need. When entering into an agreement, parties look at the mutual benefits which will be gained. The agreement terms are mostly kept as a secret between the parties and the witnesses involved. (Source: Mawu a Mulungu mu Chichewa Chalero Back Translation)

Law (2013, p. 95) writes about how the Ancient Greek Septuagint‘s translation of the Hebrew berith was used by the New Testament writers as a bridge between the Old and New Testaments (click or tap here to read more):

“Right from the start we witness the influence of the Septuagint on the earliest expressions of the Christian faith. In the New Testament, Jesus speaks of his blood being a kaine diatheke, a ‘new covenant.’ The covenant is elucidated in Hebrews 8:8-12 and other texts, but it was preserved in the words of Jesus with this language in Luke 22:20 when at the Last Supper Jesus said, ‘This cup that is poured out for you is the new covenant in my blood. Jesus’s blood was to provide the grounds for the ‘new covenant,’ in contrast to the old one his disciples knew from the Jewish scriptures (e.g., Jeremiah 31:31-34). Thus, the earliest Christians accepted the Jewish Scriptures as prophecies about Jesus and in time began to call the collection the ‘Old Testament’ and the writings about Jesus and early Christianity the ‘New Testament,’ since ‘testament’ was another word for ‘covenant.’ The covenant promises of God (berith in Hebrew) were translated in the Septuagint with the word diatheke. In classical Greek diatheke had meant ‘last will, testament,’ but in the Septuagint it is the chosen equivalent for God’s covenant with his people. The author of Hebrews plays on the double meaning, and when Luke records Jesus’ announcement at the Last Supper that his blood was instituting a ‘new covenant,’ or a ‘new testament,’ he is using the language in an explicit contrast with the old covenant, found in the Jewish scriptures. Soon, the writings that would eventually be chosen to make up the texts about the life and teachings of Jesus and the earliest expression of the Christian faith would be called the New Testament. This very distinction between the Old and New Testaments is based on the Septuagint’s language.”
