From all covetousness (apo pasēs pleonexias). Ablative case. From every kind of greedy desire for more (pleon, more, hexia, from echō, to have) an old word which we have robbed of its sinful aspects and refined to mean business thrift.
In the abundance of the things which he possesseth (en tōi perisseuein tini ek tōn huparchontōn autōi). A rather awkward Lukan idiom: “In the abounding (articular infinitive) to one out of the things belonging (articular participle) to him.”
