In other passages, for chashabh, damah, or zamam, indicating the result of mental activity, as in an intention or estimate formed after careful deliberation (compare Ecclesiasticus 18:25); In the New Testament, most, frequently for dokeo, "to be of the opinion, "suppose," literally, "seem" (Mt 3:9; 6:7; Lu 10:36, etc.). Sometimes, for logizomai, "to compute," "reckon" (Ro 2:3, etc.); sometimes, for nomizo, literally referring to what attains the force of law (nomos), and then, "to be of the opinion"; or, for phroneo, implying a thought that is cherished--a mental habit, rather than an act (Ro 12:3; 1Co 13:11). The Greek hegeomai, "to consider," implies logical deduction from premises (Ac 26:2; Php 2:6), while in Mt 1:20; 9:4, and Ac 10:19, enthumoumai, refers to the mental process itself, the thinking-out of a project, the concentration of the faculties upon the formation of a plan.
