The Greek that is translated as “(Jesus) the pioneer (and perfecter) of our faith” in English is translated as “Jesus first has opened a path for us to believe God” in Citak. (Source: Graham Ogden)
In Masai, “pioneer” is translated as “one who treads on the thorns ahead.” Nida (1972, p. xiv) explains: “Such a person goes down the pathway ahead of others and becomes the ‘thorn-treader.’ What more fitting description of the role of Jesus, who promised always to go ahead of his disciples?”
The Greek that is translated as “astonished” or “amazed” or “marvel” in English is translated in Pwo Karen as “stand up very tall.” (In John 5:20, source: David Clark)
Elsewhere it is translated as “confusing the inside of the head” (Mende), “shiver in the liver” (Uduk, Laka), “to lose one’s heart” (Mískito, Tzotzil), “to shake” (Southern Bobo Madaré), “to be with mouth open” (Panao Huánuco Quechua) (source: Bratcher / Nida), “to stand with your mouth open” (Citak) (source: Stringer 2007, p. 120), “ceasing to think with the heart” (Bulu), or “surprise in the heart” (Yamba) (source for this and one above: W. Reyburn in The Bible Translator 1959, p. 1ff.).
In Mark 5:20 and elsewhere where the astonishment is a response to listening to Jesus, the translation is “listened quietly” in Central Tarahumara, “they forgot listening” (because they were so absorbed in what they heard that they forgot everything else) in San Miguel El Grande Mixtec, “it was considered very strange by them” in Tzeltal (source: Bratcher / Nida), “in glad amazement” (to distinguish it from other kinds of amazement) (Quetzaltepec Mixe) (source: Robert Bascom), or “breath evaporated” (Mairasi) (source: Enngavoter 2004).
