The Greek in Acts 1:24 that is translated in English as “(you) know everyone’s heart” or similar is translated in Enlhet as “(you) know everyone’s innermost.” “Innermost” or valhoc is a term that is frequently used in Enlhet to describe a large variety of emotions or states of mind (for other examples see here). (Source: Jacob Loewen in The Bible Translator 1969, p. 24ff. )

It is translated as “who knowest the hearts of all men you know what the hearts of all the people in the world are like” in Lalana Chinantec, as “you know the hearts of all” in Morelos Nahuatl, as “you know what is in our hearts” in Chuj, and as “you know all people’s hearts and minds” in Isthmus Mixe.
