If when he seeth the sword come upon the land, he blow the trumpet, and warn the people;

And he see the sword coming upon the land, and sound the trumpet, and tell the people:

if he see the sword coming upon the land, and blow the trumpet, and warn the people;

And he hath seen the sword coming against the land, And hath blown with a trumpet, and hath warned the people,

If, when he sees the sword coming on the land, by sounding the horn he gives the people news of their danger;

if, when he seeth the sword come upon the land, he blow the horn, and warn the people;

and if he sees the sword approaching over the land, and he sounds the trumpet, and he announces to the people,

If what he seeth the sword come upon the land,.... Or those that kill with the sword, as the Targum; as soon as he observes a body of armed men, more or less, marching towards the borders of the land with a manifest intention to enter and invade it:
he blow the trumpet, and warn the people; warn the people by blowing the trumpet, the signal agreed on; by which they would understand that an enemy was at hand, or danger near; or warn them by word of mouth, as well as by the trumpet, where he could do it, and when it was necessary.

the sword--invaders. An appropriate illustration at the time of the invasion of Judea by Nebuchadnezzar.
