'Sustain' in the Bible

The dominion will be vast,and its prosperity will never end.He will reign on the throne of Davidand over his kingdom,to establish and sustain itwith justice and righteousness from now on and forever.The zeal of the Lord of Hosts will accomplish this.

The Lord God has given Methe tongue of those who are instructedto know how to sustain the weary with a word.He awakens Me each morning;He awakens My ear to listen like those being instructed.

And if you offer yourself to [assist] the hungryAnd satisfy the need of the afflicted,Then your light will rise in darknessAnd your gloom will become like midday.
