Threshold

Easton's Bible Dictionary (1897)

(1.) Heb. miphtan, probably a projecting beam at a higher point than the threshold proper (1 Sam. 5:4, 5; Ezek. 9:3; 10:4, 18; 46:2; 47:1); also rendered “door” and “door-post.” (2.) ‘Asuppim, pl. (Neh. 12:25), rendered correctly “storehouses” in the Revised Version. In 1 Chr. 26:15, 17 the Authorized Version retains the word as a proper name, while in the Revised Version it is translated “storehouses.”

Smith's Bible Dictionary (1863)

Of the two words so rendered is the Authorized Version, one, miphthan, seems to mean sometimes a projecting beam or corbel. (Ezekiel 9:3; 10:4,18)
