Acts 4:29

And now, Lord, behold their threatenings - It is not against us, but against thee, that they conspire: it is not to prevent the success of our preaching, but to bring to nought thy counsel: the whole of their enmity is against thee. Now, Lord, look upon it; consider this.

And grant unto thy servants - While we are endeavoring to fulfill thy counsels, and can do nothing without thee, sustain our courage, that we may proclaim thy truth with boldness and irresistible power.

Behold their threatenings - So look upon them as to grant us deliverance. They did not purpose to abandon their undertaking; they resolved to persevere; and they expected that this purpose would involve them in danger. With this purpose they implored the protection of God; they asked that he would not suffer them to be deterred from speaking boldly; and they sought that constant additional proof might be granted of the presence and power of God to confirm the truth of their message.

And grant ... - This is an instance of heroic boldness, and a determination to persevere in doing their duty to God. When we are assailed by those in power; when we are persecuted and in danger, we should commit our way unto God, and seek his aid, that we may not be deterred from the path of duty.
