Akkadian

tebû - to get up, to rise; to set out, to depart, to leave (CAD T 306, AHw. 1342)

Cf. Ugr. tbˁ ‘to go, leave, depart’, Arb. tbˁ ‘to follow’.

PS
*tbˁ - to set out, to depart (Kogan 2015:342)

Uncertain. Akk.-Ugr. *tbˁ ‘to set out, to depart’ is probably related to Arb. tbˁ ‘to follow’, but the semantic gap underlying this comparison contrasts sharply with the virtual semantic identity between Akkadian and Ugaritc.
