Psalms 119:151 - Matthew Poole's English Annotations on the Holy Bible

Thou art near to me. Thou art as ready and present to succour me as they are to molest me. Thy commandments; considered with the promises and threatenings, which are frequently annexed to them. Or, the promises, as this word seems to be used, Psalms 111:7, and elsewhere in this Psalm. And God is said to command not only his precepts, or the observation thereof, but also his covenant, Psalms 105:8, Psalms 111:9, which is a collection or body of the promises; and his loving-kindness, Psalms 42:8, which is the fountain of the promises; and his blessing, Psalms 133:3, which is the fruit of his promises; and deliverances, Psalms 44:4, which are the things promised. And therefore it is not strange if he promises be sometimes called commandments.
