Psalms 34:1

1 To David, when he changed his mouth, or his word, before Abimelech, and he drove out David, and he went forth. I shall bless the Lord in all time; ever[more] his praising be in my mouth. (To David, when he changed his face, and his words, before Abimelech, who then drove David out, and so he went forth. I shall always bless the Lord; his praises shall be in my mouth forevermore.)

Psalms 34:1 Meaning and Commentary

Psalms 34:1

I will bless the Lord at all times
That is, ascribe blessing, give honour, praise, and glory to him, both as the God of nature and providence, for every temporal mercy; and that every day, and at all times in the day; since these are renewed every morning, and continue all the day long: and as the God of grace, for all spiritual blessings; and that continually, because these last always; they are irreversible, unchangeable, and without repentance; yea, saints have reason to bless God in times of adversity as well as prosperity, since it might have been worse with them than it is; they have a mixture of mercy in all, and all things work together for their good;

his praise [shall] continually [be] in my mouth;
not the "praise" of which God is the author, but of which he is the object; which is due unto him, and is given him on account of the perfections of his nature, and the works of his hands, and the blessings of his providence and grace; this, the psalmist says, should be in his mouth: his meaning is, that he should not only retain in his heart a grateful sense of the divine favours, but should express it with his lips; should both make melody in his heart to the Lord, and vocally sing his praise; and that "continually", as long as he lived, or had any being, ( Psalms 146:2 ) .

Psalms 34:1 In-Context

1 To David, when he changed his mouth, or his word, before Abimelech, and he drove out David, and he went forth. I shall bless the Lord in all time; ever[more] his praising be in my mouth. (To David, when he changed his face, and his words, before Abimelech, who then drove David out, and so he went forth. I shall always bless the Lord; his praises shall be in my mouth forevermore.)

2 My soul shall be praised in the Lord; mild men hear, and be glad. (My soul shall have glory in the Lord; let the humble hear, and be glad.)

3 Magnify ye the Lord with me; and enhance we his name into itself (and let us exalt his name together).

4 I sought the Lord, and he heard me; and he delivered me from all my tribulations (and he rescued, or saved, me, from all of my troubles).

5 Nigh ye to him, and be ye lightened (Go ye near to him, and ye shall shine with joy); and your faces shall not be shamed.
