Meaning
from kratos, "strong" (which denotes power in activity and effect), serves as the comparative degree of agathos, "good" (good or fair, intrinsically). Kreisson is especially characteristic of the Epistle to the Hebrews, where it is used 12 times; it indicates what is (a) advantageous or useful, 1Co 7:9, 1Co 7:38, 1Co 11:17, Heb 11:40, Heb 12:24, 2Pe 2:21, Phi 1:23, where it is coupled with mallon, "more," and pollo, "much, by far," "very far better" (RV); (b) excellent, Heb 1:4, Heb 6:9, Heb 7:7, Heb 7:19, Heb 7:22, Heb 8:6, Heb 9:23, Heb 10:34, Heb 11:16, Heb 11:35.
<2,,2570 3123,kalon ... mallon> the neuter of kalos, with mallon, "more," is used in Mar 9:42, "it were better (lit., 'much better') for him if a great millstone were hanged about his neck." In verses Mar 9:43, Mar 9:45, Mar 9:47, kalos is used alone (RV, "good," for AV, "better").
Note: In Luk 5:39 the most authentic texts have chrestos, "good," instead of the comparative, chrestoteros, "better."
