The prophets all saying the same thing is spoken of as if they all spoke with the same mouth. The phrase "the words of the prophets" represents the message that the prophets declare. AT: "the prophets all declare the same good things to the king" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-metonymy]])
Here the word "them" refers to "the words of the prophets." AT: "let what you say agree with what they have said" (See: [[rc://en/ta/man/translate/figs-explicit]])
# As Yahweh lives
"as surely as Yahweh is alive." The people use this expression to show that what they say next is certainly true. This is a way of making a solemn promise. AT: "I solemnly swear" (See: [[rc://en/ta/man/translate/figs-idiom]])
# or not
The understood information may be supplied. AT: "or should we not go" (See: [[rc://en/ta/man/translate/figs-ellipsis]])
# should we go
The word "we" refers to Ahab, Jehoshaphat, and their armies but not to Micaiah. (See: [[rc://en/ta/man/translate/figs-exclusive]])
