'Host's' in the Bible

Then the men who were designated by name rose up and took the captives, and from the spoil they clothed all those who were naked; they clothed them and gave them sandals, and fed them and gave them [something to] drink, anointed them [with oil, as was a host’s duty], and led all the feeble ones on donkeys, and they brought them to Jericho, the City of Palm Trees, to their brothers (fellow descendants of Israel, i.e. Jacob). Then they returned to Samaria.
