Usage notes

Unlike English in, בְּ־ cannot easily mean into; rather, לְ־ (l'-, “to”) is generally used for that sense.
Like English in, בְּ־ is a fairly weak word; when the sense is that of being in a place, the word בְּתוֹךְ (b'tókh, “within, inside”) may be used as a stronger variant.
בְּ־ is used in forming dates using the traditional Hebrew months; for example, 17 Tammuz is “‏17 בתמוז”, literally “17 in Tammuz”. However, לְ־ (l'-, “to”) is sometimes used with the months of the Roman calendar.
בְּ־ undergoes the same vowel changes as לְ־ (l'-, “to”) and כְּ־ (k'-, “like, as”), including the merger with הַ־ (ha-, “the”); see לְ־ (l'-, “to”).
Unlike English in, בְּ־ is strictly a preposition, and always takes an object; בִּפְנִים (bif'ním, “in, inside”) is used without an object.
בְּ־ turns to בִּ־ when it's followed by a letter with a shva.
