By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name.
As the "altar" was mentioned, Hebrews 13:10, so the "sacrifice" here (cf. 1 Peter 2:5 - namely, praise and doing good, Hebrews 13:16). Compare Psalms 119:108; Romans 12:1.
By him - as Mediator of our prayers and praises (John 14:13-14); not by Jewish observances (Psalms 50:14; Psalms 50:23; Psalms 69:30-31; Psalms 107:22; Psalms 116:17). The rabbis had an old saying, 'At a future time all sacrifices shall cease, but praises shall not.'
Praise - for salvation.
Continually - not merely at fixed seasons, as those on which the legal sacrifices were offered, but all our life long.
Fruit of our lips (Isaiah 57:19; Hosea 14:2).
Giving thanks, х homologountoon (G3670)] (our lips) - 'confessing.' Bengel, The Hebrew х towdah (H8426)] is beautifully emphatic: literally acknowledgment or confession. In praising a creature, we may easily exceed the truth; but in praising God, we have only to go on confessing what He really is to us. Hence, it is impossible to exceed the truth: here is genuine praise.
