ḫaṣānu - to shelter, to receive in a friendly way (CAD Ḫ 129, AHw. 331)

SB, NA, NB lexeme. Unlikely to be autochthonous in view of the irregular ḫ coupled with the late attestation. Rather, we must be faced with WS loanword, even if the exact source of borrowing is not easy to establish (not Aramaism because of ṣ).
