“in times to come.” The Hebrew is idiomatic: “tomorrow,” meaning “in the future.”

“What do these stones mean?” The literal Hebrew is “What are these stones,” but the idiomatic meaning is, “What do these stones mean?” In the biblical culture, “remember” was not nostalgia that led to good feelings, but rather memory that helped people recall the deeds of Yahweh so people could know who He was and what the relationship was between Him and people. Then the memories led to good theology (“God acts this way.”) and then to right actions. If you have no memory, if you forget, you will eventually not know how to relate to God, which will result in bad theology, bad relationship, and a bad life (Deut. 6:12; 8:11, 18; Judg. 3:7).
