Lexham Hebrew Interlinear (LHI) explains that בך is a contraction of ב (in) and אתה (thee). We see the same idea in בכה. This translation of בך is supported by numerous others, including Young, Miller, and others. See Dead See Scrolls 1QIsa-a, Masoretic text, etc. Isaiah 26:3. Can someone help me understand this. It seems that it is so basic but I cannot find an explanation. Please feel free to refer me to a Lexicon or Grammar, as I have quite a few. Best, Gregorio
