Psalm 29:11

The Lord will give strength unto his people
His special people, his covenant people, whom he has chosen for himself; these are encompassed with infirmities, and are weak in themselves; but there is strength for them in Christ: the Lord promises it unto them, and bestows it on them, and which is a pure gift of his grace unto them; this may more especially regard that strength, power, and dominion, which will be given to the people of the most High in the latter day; since it follows, upon the account of the everlasting kingdom of Christ;

the Lord will bless his people with peace:
with internal peace, which is peculiar to them, and to which wicked men are strangers; and which arises from a comfortable apprehension of justification by the righteousness of Christ, of pardon by his blood, and atonement by his sacrifice; and is enjoyed in a way of believing; and with external peace in the latter day, when there shall be no more war with them, nor persecution of them; but there shall be abundance of peace, and that without end; and at last with eternal peace, which is the end of the perfect and upright man; and the whole is a great blessing.
