Magnify

mag'-ni-fi (Hiphil of gadhal; megaluno, "to make great," "extol," "celebrate in praise"): Used especially of exaltation of the name, mercy, and other attributes of God (Ge 19:19; 2Sa 7:26; Ps 35:27; 40:16; 70:4; Lu 1:46; Ac 10:46); of God's "word" (Ps 138:2); or of Christ (Ac 19:17; Php 1:20). Men also can be "magnified" (Jos 4:14; 1Ch 29:25, etc.). In Ro 11:13, "magnify mine office," the word (Greek, doxazo) is changed in the Revised Version (British and American) to "glorify."
