A Latin dictionary will tell you.
My first-year Latin students (in high school) learn these five, that "take the dative" for no obvious reason (to non-Latin speakers, that is):
appropinquāre , to approach, come near to; favēre , to root for, support; cōnfīdere , to have faith in, trust; nocēre , to do harm to, hurt; occurrere , to run into, encounter.
My 2nd-year students add: pārēre , to obey; parcere , to spare, be merciful to; crēdere , to trust.
(Of course, any verb that means "give, show, tell" is likely to have both a direct object in the accusative case, and an indirect object in the dative case: such as dēmōnstrāre or ostendere for to show a direct object to an indirect object; dare and trādere to give or hand over (a DO to an IO); nārrāre for to tell something (DO) to someone (IO).)
