Doctrines and Convenants 61 v. 14-27
14 Behold, I, the Lord, in the beginning blessed the waters; but in the last days, by the mouth of my servant John, I cursed the waters.
15 Wherefore, the days will come that no flesh shall be safe upon the waters.
16 And it shall be said in days to come that none is able to go up to the land of Zion upon the waters, but he that is upright in heart.
17 And, as I, the Lord, in the beginning cursed the land, even so in the last days have I blessed it, in its time, for the use of my saints, that they may partake the fatness thereof.
18 And now I give unto you a commandment that what I say unto one I say unto all, that you shall forewarn your brethren concerning these waters, that they come not in journeying upon them, lest their faith fail and they are caught in snares;

21 Wherefore, let those concerning whom I have spoken, that should take their journey in haste—again I say unto you, let them take their journey in haste.
22 And it mattereth not unto me, after a little, if it so be that they fill their mission, whether they go by water or by land; let this be as it is made known unto them according to their judgments hereafter.
23 And now, concerning my servants, Sidney Rigdon, Joseph Smith, Jun., and Oliver Cowdery, let them come not again upon the waters, save it be upon the canal, while journeying unto their homes; or in other words they shall not come upon the waters to journey, save upon the canal.
24 Behold, I, the Lord, have appointed a way for the journeying of my saints; and behold, this is the way—that after they leave the canal they shall journey by land, inasmuch as they are commanded to journey and go up unto the land of Zion;
25 And they shall do like unto the children of Israel, pitching their tents by the way.
26 And, behold, this commandment you shall give unto all your brethren.
27 Nevertheless, unto whom is given power to command the waters, unto him it is given by the Spirit to know all his ways;
