The following translations are illustrative of the contrastive expressions: “your hearts are ready but your bodies are weak” (Highland Puebla Nahuatl), “your heart is strong but you yourselves are not strong” (Central Tarahumara), “your heart has strength, but your body does not have strength” (Tzeltal), “your heart desires to do good, but your heart is weak,” in which “heart” must be used in both clauses since it not only stands for the center of the personality, but is also the symbol of typical human nature (Loma). (Source for this and all above Bratcher / Nida)
Other translations include “the mind is enthusiastic about doing what God wants it to but limited in the capacity of the body” (Ibaloi) or “Your body is tired but your inner man is not tired” (Lacandon). (Source: B. Moore / G. Turner in Notes on Translation 1967, p. 1ff.)
In Guhu-Samane an idiomatic expression with “your desire is there, but sleep has slain your body” is used. (Source: Ernest Richert in Notes on Translation December 1963: p. 4-7; reprinted in The Bible Translator 1965, p. 198ff. )
The Greek that is typically translated as “spirit” in English is translated in Warao as “obojona.” Obojona is a term that “includes the concepts of consciousness, will, attitude, attention and a few other miscellaneous notions.” (Source: Henry Osborn in The Bible Translator 1969, p. 74ff. )
The now commonly-used English idiom “The spirit is willing, but the flesh is weak” (meaning a person pretending to be harmless) was first coined in 1526 in the English New Testament translation of William Tyndale. (Source: Crystal 2010, p. 281)
For other idioms in English that were coined by Bible translation, see here.
“to beg” or “to ask,” (full expression: “to ask with one’s heart coming out,” which leaves out selfish praying, for asking with the heart out leaves no place for self to hide) (Tzotzil)
“to raise up one’s words to God” (implying an element of worship, as well as communication) (Miskito, Lacandon) (Source of this and all above: Bratcher / Nida)
Shilluk: “speak to God” (source: Nida 1964, p. 237)
Mairasi: “talk together with Great Above One (=God)” (source: Enggavoter, 2004)
Ik: waan: “beg.” Terrill Schrock (in Wycliffe Bible Translators 2016, p. 93) explains (click or tap here to read more):
What do begging and praying have to do with each other? Do you beg when you pray? Do I?
“The Ik word for ‘visitor’ is waanam, which means ‘begging person.’ Do you beg when you go visiting? The Ik do. Maybe you don’t beg, but maybe when you visit someone, you are looking for something. Maybe it’s just a listening ear.
When the Ik hear that [my wife] Amber and I are planning trip to this or that place for a certain amount of time, the letters and lists start coming. As the days dwindle before our departure, the little stack of guests grows. ‘Please, sir, remember me for the allowing: shoes, jacket (rainproof), watch, box, trousers, pens, and money for the children. Thank you, sir, for your assistance.’
“A few people come by just to greet us or spend bit of time with us. Another precious few will occasionally confide in us about their problems without asking for anything more than a listening ear. I love that.
“The other day I was in our spare bedroom praying my list of requests to God — a nice list covering most areas of my life, certainly all the points of anxiety. Then it hit me: Does God want my list, or does he want my relationship?
“I decided to try something. Instead of reading off my list of requests to God, I just talk to him about my issues without any expectation of how he should respond. I make it more about our relationship than my list, because if our personhood is like God’s personhood, then maybe God prefers our confidence and time to our lists, letters, and enumerations.”
In Luang it is translated with different shades of meaning (click or tap here to read more):
For Acts 1:14, 20:36, 21:5: kola ttieru-yawur nehla — “hold the waist and hug the neck.” (“This is the more general term for prayer and often refers to worship in prayer as opposed to petition. The Luang people spend the majority of their prayers worshiping rather than petitioning, which explains why this term often is used generically for prayer.”)
For Acts 1:14, 28:9: sumbiani — “pray.” (“This term is also used generically for ‘prayer’. When praying is referred to several times in close proximity, it serves as a variation for kola ttieru-yawur nehla, in keeping with Luang discourse style. It is also used when a prayer is made up of many requests.”)
For Acts 8:15, 12:5: polu-waka — “call-ask.” (“This is a term for petition that is used especially when the need is very intense.”)

Following are a number of back-translations of Mark 14:38:
Uma: “Keep watch and pray, so that you [plural] don’t get temptation. In your hearts you want to do what is true, but you are unable because mankind is weak.'” (Source: Uma Back Translation)
Yakan: “Watch out and pray to God that you (pl.) will not be carried-along by temptation/tempters. The liver thinks but the body cannot do it.'” (Source: Yakan Back Translation)
Western Bukidnon Manobo: “And Jesus said to them, ‘Don’t go to sleep, but rather pray so that you might be able to avoid testing. Your breath wants to follow, but your body is weak.'” (Source: Western Bukidnon Manobo Back Translation)
Kankanaey: “Don’t you (pl.) be-sleeping, but rather pray in order that you will not be successfully-tempted. Because your motives are admittedly right, but your bodies are weak.'” (Source: Kankanaey Back Translation)
Tagbanwa: “It would be good for you (pl.) to overcome your sleepiness and pray, so that you won’t be defeated by evil if/when your believing-in/obeying me is tested. Because as for your mind/inner-being, you truly want to believe/obey, but the problem is the will of your body which as it were doesn’t want to obey for it is weak.'” (Source: Tagbanwa Back Translation)
