Draw out also the spear
An offensive weapon; expressive of the vengeance which God sometimes takes of the enemies of his people, when he bends his bow, shoots his arrows, whets his glittering sword, and his hand takes hold of judgment;
and stop [the way] against them that persecute me;
that they might not overtake him; God can hinder, and he sometimes does hinder persecutors from overtaking his people in their straits; and as he hedges up their way with thorns, that they cannot proceed as they have begun, so he hedges up the way of their enemies; interposes himself and his power, and is a wall of fire about them; a wall for the defence and security of his saints, and a wall of fire for the consumption of those that rise up against them. The words may be rendered, "draw out the spear and sword, to meet those that persecute me" F16; for (rygo) is a noun, and signifies a sword shut up in its scabbard; from whence "sagaris" comes, which is kind of a sword;
say unto my soul, I [am] thy salvation;
Christ is the salvation of his people; he is the only person appointed, provided, promised, and sent to be the Saviour; and he is the alone author of salvation it is wrought out by him, and it is in him, and in him only; and therefore he is called their salvation, and the salvation of God: and they are interested in the salvation which is in him; it was designed, prepared, and wrought out for them, and for them only; and is applied unto them by the Spirit, and they shall perfectly enjoy it to all eternity: find yet sometimes they are at a loss about their interest in it, and desire might be made known unto them, which was the case of the psalmist here; they, as he, see their necessity it, and that there is no comfort nor safety without it they are wonderfully delighted with the excellency of it, that it is so great in itself, so suitable to them, so complete and perfect, and of an everlasting duration yet, what through the hidings of God's face, the temptations of Satan, the greatness of their sins, and the prevalence of unbelief, they cannot tell how to believe their interest in it; yet most earnestly desire the Lord would show it to them, and assure them of it; which favour, when granted, is by the witnessings of the Spirit to their spirits, that they are the children of God, and the redeemed of the Lamb: and this is said particularly to them; it is not a discovery of salvation by Christ in general; that they have before; but it is a saying to their souls, that it is theirs; and when this is spoken bathe to the soul by the Spirit of God, it is effectual; and removes unbelief at once, and fills with joy unspeakable and full of glory.
