Rev., that no advantage may be gained over us. The verb, from pleon more, and ecw to have, appears in the noun pleonexia greed of gain, covetousness. See on Romans 1:29.

Are ignorant - devices [α γ ν ο ο υ μ ε ν - ν ο η μ α τ α]. A paronomasia (see on Romans 1:29-31). As nearly as possible, "not know his knowing plots."
