In God I will praise his word— Truth, and faithfulness to his promises, are attributes which dwell in, or belong to God. God had promised David the kingdom of Israel, and therefore in God he would praise his word or promise: i.e. under his protection and by trusting in his power, even amidst the greatest enemies, he would celebrate the praises of his truth and goodness; not doubting but that God would, in due time, accomplish his promise: for it follows, In God will I trust; I will not fear what man can do.
