One translation of Numbers 12:2 says:
And they said, “Has the Lord indeed spoken only through Moses? Has he not spoken through us also?” And the Lord heard it.
In the interlinear Bible I see the Hebrew word for "built" בָּ֣נוּ or bā·nū in the verse without the Strong's Hebrew number 1129 above it. It is interpreted as "through us".
In other passages this same word is translated as "built". http://biblehub.com/hebrew/banu_1129.htm
I'm wondering if someone could help me understand why this is interpreted as through us instead of built? Is this the way things are built?
